General Description
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 switching losses present in traditional charge pumps or inductive boost circuits. The MIC2845A provides six linear drivers channels which maintain constant current for up to six LEDs. It 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.
