MIC2860-2PYD6 TR

The MIC2860-2PYD6 TR 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 ≤±0.5%, which ensures uniform display illumination under all conditions. The WLEDs brightness is externally preset by a resistor and dimmed using PWM interface operating down to less than 1% duty cycle.

• High efficiency (no switching losses)
• PWM frequency as low as 250Hz
• Current accuracy better than 1% typical
