MIC2845A Datasheet (Micrel Semiconductor) - High Efficiency 6 Channel Linear WLED Driver

MIC2845A, High Efficiency 6 Channel Linear WLED Driver

The MIC2845A is a high efficiency White LED (WLED) driver designed to drive up to six LEDs, greatly extending battery life for portable display backlighting, keypad backlighting, and camera flash in mobile devices.

The MIC2845A provides the highest possible efficiency as this architecture has no swi

MIC2845A Features

* a typical dropout of 40mV at 20mA. This allows the LEDs to be driven directly from the battery eliminating switching noise/losses present with the use of boost circuitry. The MIC2845A features Dynamic Average Matching™ (DAM™) which is specifically designed to provide optimum matching across all WLED
