Microchip MIC2860-2PYC6-TR LED Driver IC, 3 → 5.5 V 6-Pin SC70

The Microchip High efficiency white LED driver is designed to drive two WLEDs and significantly extend battery life for portable display and keypad backlighting in low-cost mobile devices. The architecture provides the highest possible efficiency by eliminating switching losses found in traditional charge pumps or inductive boost circuits. It features a typical dropout of 52 mV at 30.2 mA per channel, allowing the WLEDs to be driven directly from the battery, eliminating switching noise and losses associated with boost circuitry.
