MIC2846A規(guī)格書(shū)詳情
General Description
The MIC2846A is a high efficiency White LED (WLED) driver featuring two low quiescent current LDOs. It is designed to drive up to six LEDs and greatly extend battery life for portable display backlighting and keypad backlighting in mobile devices. The MIC2846A 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 MIC2846A allows the LEDs to be driven directly from the battery eliminating switching noise and losses present with the use of boost circuitry.
