The is a 2-channel high efficiency white LED WLED Driver designed to drive two WLEDs and greatly extend battery life for many applications. The MIC2860-2P architecture provides the highest possible efficiency by eliminating switching losses present in traditional charge pumps or inductive boost circuits. It features a typical dropout of 52mV at 30.2mA per channel. This allows the WLEDs to be driven directly from the battery eliminating switching noise and losses present with the use of boost circuitry. The two channels have typical matching of
- .
- High efficiency no switching losses
- .
- PWM frequency as low as 250Hz
- .
- Current accuracy better than 1% typical
