SC621A LED Light Management Unit POWER MANAGEMENT Features „ „ „ „ „ „ „ „ „ „ „ „ „ „ „ „ Charge Pump, 4 LEDs, 400mA Flash LED, Dual LDOs, and I2C Interface Description The SC621A is a high efficiency charge pump LED driver using Semtech’s proprietary mAhXLifeTM technology. Performance is optimized for use in single-cell Li-ion battery applications. The charge pump provides backlight current in conjunction with four matched current sinks. It also can supply continuous or bursted current to a flash LED using the dedicated flash driver current sink. The load and supply conditions determine whether the charge pump operates in 1x, 1.5x, or 2x mode. An optional fading feature that gradually adjusts the backlight current is provided to simplify control software.
