说明

• Typical Application for the SC2545 is a high performance dual PWM controller. It is designed to convert a wide ranged input voltage down to two independent output rails. The SC2545 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. The PWM operations of the two channels are 180 degree out of phase which can greatly reduce the size and the cost of the input capacitors
