The CXAC8544 is a high performance AC/DC power supply controller for battery charger and adapter applications. The device uses Pulse Frequency Modulation(PFM) method to build discontinuous conduction mode (DCM) flyback power supplies. The CXAC8544 provides accurate constant voltage, constant current (CV/CC) regulation while removing the opto-coupler and secondary control circuitry. It also eliminates the need of loop compensation circuitry while maintaining stability. The CXAC8544 achieves excellent regulation and high average efficiency, yet meets the requirement for no-load consumption less than 30mW.
