MIC2860-P
High Efficiency 2 Channel WLED Driver
with PWM Control
General Description
The MIC2860-2P is a 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. 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.
The MIC2860-2P is available in Thin SOT-23 and SC-70
six pin packages with a junction temperature range of
−40°C
to +125°C.
