Description
General part information
MIC4801 Series
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 LEDs in various lighting applications. The MIC4801 provides the highest possible efficiency as this architecture has no switching losses present in traditional charge pumps or inductive boost circuits. It 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 helps ensure uniform display illumination under all conditions. The brightness is controlled through an Ultra Fast PWM™ Control interface operating down to less than 1% duty cycle.
The MIC4801 is available in an 8-pin SOIC package with a junction temperature range of -40°C to +125°C.
