Worcester, MA – December 14, 2009 — Allegro MicroSystems, Inc. introduces a new off-line LED driver IC series targeted at the residential and commercial lighting markets. The LC5205D and LC5210D devices include both a main controller integrated circuit (MIC) and a power MOSFET. The high voltage capability allows direct connection to a wide range of supply voltages ranging from 25 to 400 V (recommended).
The controller chip and N-MOSFET are both housed in an 8-pin DIP package which enables a small driver board design. The controller chip utilizes the proprietary high voltage BCD process of which the low operating current and high voltage capability allow direct connection of the supply voltage pin to the high voltage supply source, unlike other low voltage controller chip solutions. Allegro’s solution reduces the component count and improves the overall reliability of the design.
In addition to these key features, over-current and thermal shutdown protections secure the LED driver design’s reliability. The package is a standard 8-pin DIP, with pin 7 removed for greater creepage distance from the supply pin.
