- Typical Application for MIC2842A: High Efficiency 4 Channel WLED Driver with DAM and Single Wire Digital Control. The MIC2842A is a high efficiency White LED (WLED) driver designed to drive up to four LEDs and greatly extend battery life for portable display backlighting, and keypad backlighting in mobile devices. The MIC2842A architecture provides the highest possible efficiency by eliminating switching losses present in traditional charge pumps or inductive boost circuits. With a typical dropout of 40mV at 20mA, the MIC2842A allows the LEDs to be driven directly from the battery eliminating switching noise and losses present with the use of boost circuitry
