MIC4801 High Efficiency 600mA Single Channel Linear WLED Driver

The MIC4801 is a high efficiency White LED (WLED) driver designed to drive a single LED up to 600mA. The MIC4801 constant current driver is designed to drive high power LED’s in various lighting applications. The MIC4801 provides the highest possible efficiency as this architecture has no switching .

MIC4801 Features

* a typical dropout of 130mV at 400mA. This allows the LEDs to be driven directly from the voltage source eliminating switching noise/losses present with the use of boost circuitry. The high accuracy (±1% typical) current regulated WLED channel ensures uniform display illumination under all conditions
