PHOENIX, Ariz. – March 23, 2010 – ON Semiconductor (Nasdaq: ONNN) a premier supplier of high performance, energy efficient silicon solutions for green electronics has extended its product portfolio, with the introduction of five new CMOS linear voltage regulator families. The NCP69x families are optimized for use in low current consumption portable battery-powered and ‘always on’ applications such as cable modems, satellite receivers, digital-set-top boxes and electricity meters.

The NCP690, NCP691, and NCP692 are Very Low Dropout (VLDO) 1 A regulator devices available with an adjustable output voltage from 5.0 V down to 1.25 V or in fixed voltage versions. The devices offer a power supply rejection ratio (PSRR) of 62 dB, low quiescent current (145 uA typical) and low noise (50 µVrms) operation, as well as short circuit and thermal protection. They have greatly enhanced electro-static discharge (ESD) protection of 4 kV compared to standard CMOS LDOs and are designed to be utilized with low cost ceramic capacitors. The NCP691 includes an enable-low function, while the NCP692 has an enable-high function.

The NCP693 1 A regulator operates with a supply current of only 65 µA at no load, and a standby mode with a supply current less than 0.15 µA, selected by a chip enable pin. Standard voltage versions are 0.8 V, 1.0 V, 1.2 V, 2.5 V and 3.3 V. This series is complemented by the NCP694, which is an Ultra Low Dropout (ULDO) 1 A regulator for applications where there is a small differential between the input and output voltage. It offers -3 mV (typical) load regulation, and a 60 μA (typical) quiescent current. A ripple rejection of 70 dB (typical), along with a current limit and thermal protection makes this a very robust and versatile device. It is available in an adjustable version with a minimum output voltage of 1.0 V, and in fixed voltage options of 0.8 V, 1.0 V, 1.2 V, 2.5 V, and 3.3 V.

“With greater emphasis being placed on energy efficient designs, engineers need to be able to specify lower voltages” states Mike Paquette, Director of the Regulation Business Unit at ON Semiconductor. “With the NCP690, NCP691, and NCP692 1 A linear voltage regulators we are able to offer a high performance solution for 1.5 V rails. By selecting the NCP693 and NCP694 our customers can add a sub 1.2 V rail to their design without needing to rely on a switcher and the associated peripheral components. This means the design will not be as complicated or electrically noisy and will occupy less board space, as well as being more cost effective to implement.”

Packaging and Pricing

The NCP690, NCP691 and NCP692 are offered in 6-lead, 3 mm x 3 mm DFN packages. The NCP693 comes in a 1.8 mm x 2.0 mm DFN package. The NCP694 is housed in 6-pin HSON and 5-pin SOT-89 packages. Depending on the device and the package selected, prices range from $0.41 to $0.55 in 10,000 unit quantities.

Three Scalable Reference Designs Support Different Line Voltage Ranges and Offer High Power Factor (> 0.95) over a Wide Range of AC Input Voltage

APPLIED POWER ELECTRONICS CONFERENCE (APEC), PALM SPRINGS, Calif. - Booth # 315 – Feb. 22, 2010 –ON Semiconductor (Nasdaq: ONNN)a premier supplier of high performance, energy efficient silicon solutions for green electronics, today announced the launch of a new power factor corrected dimmable LED driver for residential and commercial lighting applications.

Housed in a compact 8-pin surface mount package, the NCL30000 achieves high power factor (> 0.95) in a single-stage topology by using a critical conduction mode (CrM) flyback architecture, thereby eliminating the need for a DC-DC conversion stage. Constant on-time CrM operation is particularly suited to isolated flyback LED applications, as the control scheme is straightforward and very high efficiency can be achieved - even at low power levels. This is important in LED lighting in order to support compliance with regulatory requirements and meet overall system efficacy requirements.

Typical applications include LED driver power supplies, LED-based down lights, TRIAC dimmable LED-based lamps and power factor corrected constant voltage supplies. This device is compatible with both leading edge TRIAC-based and trailing edge transistor-based dimmers. Depending on the dimmer used, the LED output can be controlled down to < 2 percent.

Three up to 15 W reference designs are provided and are intended to drive from 4-15 LEDs at 350 mA. They can however, be easily modified to support power levels ranging from 5 W to 30 W:

NCL30000LED1GEVB: 115 Vac version, 90 to 135 Vac input line (Dimmable)
NCL30000LED2GEVB: 230 Vac version, 180 to 265 Vac (TRIAC Dimmable)
NCL30000LED3GEVB: Extended universal version, 90 to 305 Vac

An operating temperature range of -40°C to +125°C ensures the NCL30000 can be used across environmental operating ranges specified in the majority of solid state lighting applications. The NCL30000 has a low startup current of 24 micro amps (µA) (typical) and a low operating current of 2 milli amps (mA) (typical) that helps support high efficiency designs.

Other key features of the NCL30000 include a programmable on time limiter, zero current detect sense block, gate driver, plus all other pulse width modulation (PWM) circuitry and protection functions needed to implement a CrM switch mode power supply. The NCL30000 is the key device in a fully tested, GreenPoint® reference design for offline high power factor triac dimmable LED drivers intended for ENERGY STAR® commercial and residential luminaires. A live demonstration of this GreenPoint design is featured at the ON Semiconductor APEC booth #315 at APEC, from Feb. 22-25, 2010 in Palm Springs, Calif., and the reference design documentation can be found along with the other reference designs listed above on the ON Semiconductor website.

“Our customers have a need for dimmable LED driver solutions that are compatible with existing wiring and controls,” said Christophe Warin, AC-DC business unit manager at ON Semiconductor. ”The NCL30000 offers excellent dimming performance down to greater than 2 percent. This device is ideally suited for isolated flyback but can also be used with non-isolated buck topologies.”

Packaging and Pricing

The Pb, halogen and BFR free NCL30000 is RoHS compliant and is available in an eight-pin SOIC package. It is priced at $0.45 per unit in 10,000 unit quantities. Samples are available now. Projected lead-time for production quantities is currently eight to 12 weeks after receipt of order (ARO).

Controllers Offer High Efficiency and Low Standby Power Consumption in Wide Range of AC-DC Adaptor Applications

APPLIED POWER ELECTRONICS CONFERENCE (APEC), PALM SPRINGS, Calif. - Booth # 315 – Feb. 22, 2010 – ON Semiconductor (Nasdaq: ONNN) a premier supplier of high performance, energy efficient silicon solutions for green electronics today announced the introduction of the NCP1237, NCP1238 and NCP1288 fixed-frequency, current-mode controller ICs. Targeted at AC-DC adapter applications for laptop/notebook computers, LCD displays, printers, and household consumer electronics, the new controllers are available in a choice of frequency options with single or dual level over current thresholds. The standard device has a built-in 65 kHz oscillator, with 100 kHz and 133 kHz versions supplied on request.

The proprietary Soft−Skip™ mode utilized by these ICs ramp the peak current gradually during skip mode, reducing the risk of audible noise. This allows additional component savings, along with easing the design and manufacture of the transformer. Combining this with a frequency fold-back function, the new controllers deliver high efficiency levels in light load conditions, while minimizing input power during no load conditions.

The Dynamic Self−Supply (DSS) function of the NCP1237 and NCP1238 provide an integrated start-up current source that intelligently handles start-up and line transient events. This simplifies the design of the auxiliary supply, reducing the size of the VCC capacitor. To minimize external component count, the controllers integrate brown-out, over-power compensation and ramp compensation, allowing a compact solution to be designed.

The new fixed-frequency, current-mode controller ICs have an operational temperature range of −40 °C to +125 °C and are offered in a compact SOIC-7 package.

“With utility bills continuing to increase and concerns about the environment growing, it is vital to use electrical power at the greatest possible rates of efficiency,” said Christophe Warin, AC-DC business unit manager at ON Semiconductor. “The NCP1237, NCP1238 and NCP1288 are highly integrated solutions that will allow engineers to develop power system designs that maintain strong reliability, have a low bill-of-materials and do not waste energy when the product is in standby mode.”

The NCP1237 controller will be featured in a live demo at the ON Semiconductor booth (#315) during APEC, which takes place Feb. 22-25, 2010 in Palm Springs, Calif.

Reference designs simplify development of MR16 format products and LED-based

Phoenix, Ariz. – Nov. 24, 2009 - ON Semiconductor (Nasdaq: ONNN), a leading global supplier of high performance, energy efficient, silicon solutions for green electronics has launched two new GreenPoint® reference designs that will speed and simplify the development of high-efficiency LED-based lighting applications.

Configured in size and features for MR16 LED replacements, the first reference design describes a built and tested 3 watt (W) to 5 W LED driver solution for driving high-brightness LEDS (HB-LEDs). The second design is targeted at designers looking to achieve compliance with the ENERGY STAR® 1.1 requirements for Solid State Lighting (SSL) in residential luminaire applications and describes a built and tested off-line GreenPoint solution for an isolated 8 W constant current LED driver.

Each of the new reference designs addresses all of the functional blocks needed to create a complete application and is available as a package that includes description, schematics, bill-of-materials (BoM), Gerber files and evaluation guidelines.

The MR16 reference design is based on a buck-boost topology using ON Semiconductor’s NCP3065 switching regulator operating at around 150 kilohertz (kHz) in a non-isolated constant current configuration. Suitable for 12 Vac or 12 Vdc applications such as track lighting, automotive lighting and landscape lighting, the circuit delivers flat current regulation irrespective of input line and output LED voltage variation. It also features a unique auto-detect circuit that allows input from a 12 Vdc or 12 Vac supply while maintaining the targeted output current. A reference design evaluation board is available on the ON Semiconductor website at www.onsemi.com.

ON Semiconductor’s off-line LED Driver GreenPoint reference design for ENERGY STAR residential LED luminaires has been optimized to drive between one and eight high-power LEDs in applications such as portable desk lamps, under-cabinet lighting and outdoor porch lights. This reference design uses a novel circuit configuration to achieve a power factor of >0.85 at 115 Vac without the addition of an extra passive power factor correction network. This reduces components count and easily meets the residential power factor requirements. The design operates from a 90 Vac – 265 Vac universal input and is built around the ON Semiconductor NCP1014 switcher IC, which integrates a fixed-frequency current mode controller with a 700 V MOSFET.

“The market for solid state lighting continues to grow as new and traditional manufacturers look to capitalize on the performance, cost, reliability and efficiency benefits that LEDs offer over conventional alternatives,” said Laurent Jenck, ON Semiconductor’s marketing director for power supply applications. “These new GreenPoint reference designs allow designers of new and emerging lighting applications to dramatically reduce development times by providing a proven and tested solution to driving high brightness LEDs as efficiently as possible.”
