Integrated LMU eases smart phone design

Ideal for I2 C-based high performance smart phones and other mobile devices that require the integration of two camera modules, the AAT2862 lighting management unit (LMU) drives up to eight LEDs and LDOs linear regulators. The part features an input voltage of 2.7 to 5.5 V, an operating frequency of 1 MHz, a tri-mode charge pump that automatically switches between 1x, 1.5x, and 2x modes, and three programmable automatic fade-in/fade-out times for backlight control.

The eight LED outputs are programmable from 500 μA up to 30 mA. The output of each LDO is programmable via the I2 C serial interface to any of 16 voltages between 1.2 and 3.3 V. The part is optimized for single-cell Li-ion/polymer systems. ($1.81 ea/1,000 — available now.)
