Microchip MIC4802YME-TR MOSFET Gate Driver 1, 800 mA, 3 → 5.5V 8-Pin, SOIC [MIC4802YME-TR]; 598-309
Liên hệ
The Microchip High efficiency White LED (WLED) driver designed to drive a single LED up to 800mA. The constant current driver is designed to drive high power LED's in various lighting applications. It features a typical dropout of 280mV at 800mA. This allows the LEDs to be driven directly from the voltage source eliminating switching noise/losses present with the use of boost circuitry.
