MIC4802 WLED Drivers

Microchip Technology MIC4802 White LED (WLED) Drivers are high-power and high-efficiency LED drivers designed to drive a single LED up to 800mA. This driver's architecture has no switching losses in traditional charge pumps or inductive boost circuits. The MIC4802 drivers allow 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 to 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 MIC4802 WLED drivers are available in the 8-pin SOIC Epad package with a junction temperature range of -40°C to 125°C.
