CXAC8544二次控制电路提供精确的恒压恒流（CV/CC）调节环路补偿电路保持稳定性紧凑型CV调节性能脉冲频率调制PFM方法建立不连续导通模式DCM反激电源

产品简介

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.
