MIC2843 Datasheet (Micrel Semiconductor) - High-Efficiency 6-Channel Linear WLED Driver

MIC2843, High-Efficiency 6-Channel Linear WLED Driver

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.

The MIC2843 provides the highest possible efficiency as this architecture has

MIC2843 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
