The MAX8830 light management IC integrates a 400mA (guaranteed) PWM DC-DC step-up converter, a 320mA white LED camera flash current sink, and four programmable LED current sinks. The internal 1MHz step-up converter features an internal switching MOSFET and synchronous rectifier to improve efficiency and minimize external component count. The camera flash output current and maximum timer is programmable through I²C. Each LED current is individually regulated to a programmable level (from off to 10mA in 32 steps) and is completely independent of each other.

An I²C interface controls individual on/off of all outputs, step-up output voltage setting, movie/flash current, flash timer duration settings, and individual LED current sink settings.

The MAX8830 is available in a 16-bump UCSP™ package (2.5mm x 2.5mm).
