Part Details:

19-0782; Rev 1; 6/08 LED Light Management IC in 2.5mm x 2.5mm UCSP MAX8830 General Description Features The MAX8830 light management IC integrates a 400mA Step-Up DC-DC Converter (guaranteed) PWM DC-DC step-up converter, a 320mA 400mA Guaranteed Output Current white LED camera flash current sink, and four program- Over 90% Efficiency mable LED current sinks. The internal 1MHz step-up On-Chip FET and Synchronous Rectifier converter features an internal switching MOSFET andsynchronous rectifier to improve efficiency and minimize Fixed 1MHz PWM Switching external component count. The camera flash output cur- Small 2.2µH to 10µH Inductor rent and maximum timer is programmable through I2C. I2C-Programmable VOUT (3.8V to 5.2V and Off in Each LED current is individually regulated to a program- 16 Steps) mable level (from off to 10mA in 32 steps) and is com- Flash LED Current Sink pletely independent of each other. I2C-Programmable Flash Output Current (Off to An I2C interface controls individual on/off of all outputs, 320mA in 32 Steps) step-up output voltage setting, movie/flash current, I2C-Programmable Flash Maximum Timer (0.5s, flash timer duration settings, and individual LED current 1.0s, 1.5s, or 2.0s) sink settings. I2C-Programmable Movie Output Current (Off to The MAX8830 is available in a 16-bump UCSPTM pack- 160mA in 16 Steps) age (2.5mm x 2.5mm).
