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 program-
mable 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 cur-
rent and maximum timer is programmable through I2C.
Each LED current is individually regulated to a program-
mable level (from off to 10mA in 32 steps) and is com-
pletely 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? pack-
age (2.5mm x 2.5mm).
