SC621: LED Light Management Unit With SemWire™ Interface | Semtech

The SC621 is a high ei ciency Charge Pump LED Driver using Semtechs proprietary mAhXLif 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 l ash LED using the dedicated l ash 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. A l ash-timeout feature disables the l ash if active for longer than 1 second. The SC621 also provides two low-dropout, low-noise linear Regulators for powering a camera module or other peripheral circuits. By Semtech Corporation
