... General Description The MIC2860- high efficiency white LED (WLED) driver designed to drive two WLEDs and greatly extend battery life for portable display backlighting, and keypad backlighting in low cost mobile devices. The MIC2860-2P architecture provides the highest possible efficiency by eliminating switching losses present in traditional charge pumps or inductive boost circuits ...

... If dimming is desired the MIC2860-2P can dim via a PWM signal. Block Diagram As shown in Figure 1, the MIC2860-2P consists of two current sinks with the peak current determined by R The linear drivers have a designated control block for enabling and dimming of the WLEDs. The MIC2860-2P is controlled by the PWM control block that receives PWM signals for dimming ...

... Micrel Inc. Application Information PWM Dimming Interface The MIC2860-2P can receive PWM signals from the EN pin for WLED dimming. Dimming is generated by pulsing the WLEDs on and off in synchronization with the PWM signal. The MIC2860-2P incorporates an internal shutdown delay to ensure that the internal control circuitry remains active during PWM dimming for optimum performance ...
