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.

Dynamic Averaged Matching™ (DAM™) which is specifically designed to get the optimum matching despite process variations. This ensures a typical matching of ±1.5% between all six LED channels. The LED brightness is preset by an external resistor and can be dimmed using a single-wire digital control. The digital interface takes commands from digital programming pulses to change the brightness in a logarithmic scale similar to the eye’s perception of brightness. The singlewire digital brightness co.
