Description
The MIC2843 is a high-efficiency linear white LED (WLED) driver designed to drive up to six WLEDs, greatly extending battery life for portable display backlighting, keypad backlighting, and camera flash in mobile devices.
Features
- a typical dropout of less than 40mV at 20mA. This allows the WLEDs to be driven directly from the battery eliminating switching noise/losses present with the use of boost circuitry. The six channels are matched better than ±3% typical, ensuring uniform display illumination under all conditions. The brightness is controlled through an Ultra Fast PWM™ interface operating down to less than 1% duty cycle. The MIC2843 is available in the 2mm x 2mm 10-pin Thin ® MLF leadless package with a junction te.
