Cxac8541sg is a high performance AC / DC conversion control chip, suitable for chargers and other adapters. It uses PFM modulation technology to provide precise constant voltage / constant current (CV / CC) control loop. Using cxac8541 can save optocoupler, secondary feedback control and loop compensation. Cxac8541 includes undervoltage locking, overvoltage protection, leading edge blanking, overcurrent protection, overheating protection with hysteresis characteristics, loop open circuit protection and line loss compensation. At 265vac input, the no-load power consumption can be less than 200MW
