TS3011 High Speed comparator: when response time matters

FredericLannoo — Tue, 09 Nov 2021 17:06:10 GMT

Current Revision posted to Documents by FredericLannoo on 11/9/2021 5:06:10 PM

ST’s TS3011 single comparator achieves a propagation delay of 8ns while consuming only 470 µA of supply current at 5V, which is 50% lower than other solutions in the market. This unmatched energy efficiency allows ST customers to design products that use less power and have less impact on the environment.

ST’s high-speed voltage comparator addresses applications where fast response time is critical, such as in data communications equipment. When a noise occurs in the signal, for example, minimized delay helps ensure instant data recovery and thus maintain failure-free communication traffic flow. Fast-response comparators can also find use in pulse-width modulation for audio amplifiers or as output buffers in oscilloscopes and analog-to-digital converters.

SPV1020 is a monolithic DC-DC boost converter designed to maximize the power generated by photovoltaic panels independently of temperature and amount of solar radiation.

The optimization of the power conversion is obtained with an embedded logic which performs the MPPT (max power point tracking) algorithm on the PV cells connected to the converter.

One or more converters can be housed in the connection box of PV panels, replacing the bypass diodes, and thanks to the fact that the maximum power point is locally computed, the efficiency at system level will be higher than the one of conventional topologies, where the MPP is computed in the main centralized inverter.

For a cost effective application solution and miniaturization needs, SPV1020 embeds the power MOSFETs for active switches and synchronous rectification, minimizing the number of external devices. Furthermore, the 4 phase interleaved topology of the DC-DC converter allows to avoid the use electrolytic capacitors, which would severely limit the lifetime.

It works at fixed frequency in PWM mode, where the duty cycle is controlled by the embedded logic running a Perturb&Observe MPPT algorithm. The switching frequency, internally generated and set by default at 100 kHz, is externally tunable, while the duty cycle can range from 5% to 90% with a step of 0.2%.

Safety of the application is guaranteed by stopping the drivers in case of output overvoltage or overtemperature.

The HVLED805 is a high-voltage primary switcher intended for operating directly from the rectified mains with minimum external parts to provide an efficient, compact and cost effective solution for LED driving. It combines a high-performance low-voltage PWM controller chip and an 800V, avalanche-rugged power MOSFET, in the same package.

The PWM is a current-mode controller IC specifically designed for ZVS (Zero Voltage Switching) fly-back LED drivers, with constant output current (CC) regulation using primary-sensing feedback. This eliminates the need for the opto-coupler, the secondary voltage reference, as well as the current sense on the secondary side, still maintaining a good LED current accuracy. Moreover it guarantees a safe operation when short circuit of one or more LEDs occurs.

In addition, the device can also provide a constant output voltage regulation (CV): it makes the application able to work safely when the LED string opens due to a failure.

Quasi-resonant operation is achieved by means of a transformer demagnetization sensing input that triggers MOSFET’s turn-on. This input serves also as both output voltage monitor, to perform CV regulation, and input voltage monitor, to achieve mains-independent CC regulation (line voltage feed forward).

The maximum switching frequency is top-limited below 166 kHz, so that at medium-light load a special function automatically lowers the operating frequency still maintaining the operation as close to ZVS as possible. At very light load, the device enters a controlled burst-mode operation that, along with the built-in high-voltage start-up circuit and the low operating current of the device, helps minimize the residual input consumption.

Although an auxiliary winding is required in the transformer to correctly perform CV/CC regulation, the chip is able to power itself directly from the rectified mains. This is useful especially during CC regulation, where the fly-back voltage generated by the winding drops.

In addition to these functions that optimize power handling under different operating conditions, the device offers protection features that considerably increase end-product’s safety and reliability: auxiliary winding disconnection or brownout detection and shorted secondary rectifier or transformer’s saturation detection. All of them are auto restart mode.

Key Features

800 V, avalanche rugged internal power MOSFET
5% accuracy on constant LED output current with primary control
Optocoupler not needed
Quasi-resonant (QR) zero voltage switching (ZVS) operation
Internal HV start-up circuit
Open or short LED string management
Automatic self supply
Input voltage feed-forward for mains independent cc regulation

Press Release - ST Microelectronics - Package Innovation from STMicroelectronics Unlocks Performance Boost for High-Frequency Power Devices

Plastic air-cavity package for next-generation RF power transistors replaces conventional ceramic, enabling higher gain and output with weight and bill-of-materials savings

Geneva, March 10,2010 - STMicroelectronics (NYSE: STM), a leader in power applications, has announced innovative plastic air-cavity packages that enable high-power transistors for Radio-Frequency (RF) applications such as transceivers, broadcast equipment and MRI scanners to deliver performance and cost advantages over alternative devices in ceramic packages.

Air-cavity packages provide high electrical isolation for silicon die, and are well suited for high-frequency, high-power applications. Whereas the traditional package body is typically ceramic, to withstand high-temperature soldering during package assembly, this new air-cavity technology now enables lower thermal resistance, lower weight, and reduced cost compared to devices in ceramic packages.

ST’s new STAC plastic packages achieve junction-to-case thermal resistance (RTH) of 0.28°C/W, which is some 20% better than comparable ceramic packages. This improves heat removal from the die during normal operation, allowing transistors to deliver increased gain and greater output power while simultaneously increasing reliability. In addition, the Mean Time To Failure (MTTF) for devices in the new packages is up to four-times longer than comparable devices in ceramic packages. In addition, 75% lighter weight delivers valuable savings for designers of equipment such as avionics systems or mobile devices. Two versions are available, matching the dimensions of industry-standard solder-down (flangeless) or bolt-down ceramic packages to enable direct replacement in existing designs.

ST has introduced three new devices for applications up to 250MHz using this new package technology, including the only 100V VHF MOSFET currently on the market. The 100V STAC3932B/F, in bolt-down or flangeless configurations, has 26dB linear gain and can sustain pulse-power output up to 900W. The STAC2932B/F and STAC2942B/F are 50V devices having linear gain and continuous rated output power of 20dB/400W and 21dB/450W respectively. The devices achieve nominal efficiency from 68% to 75%, compared to around 55% for the nearest ceramic alternatives.

The bolt-down version of the device is in full production; the flangeless variant is now sampling and will be in full production in Q2 2010. Prices for the power transistors in the new plastic air-cavity packaging start at $48 for the STAC2932B/F in quantities over 25,000 units.
