The SC2544 is a high performance dual PWM controller. It is designed to convert a wide ranged input voltage down to two independent output rails. The SC2544 support “peel off ” tracking for the two outputs at start up which means the two outputs ramp up together till the one with lower output level reaching the regulation.
