CXAC85173是一个通过检测辅助线圈电压，实现自动调节恒压恒流输出的PSR控制器。它通过自动在PWM模式和PFM模式之间切换实现高的AC-DC转换效率。CXAC85173内置了热关断、过流、输出过压及输入过压保护功能。The CXAC85173 is a Constant-Voltage (CV) and Constant-Current (CC) regulator controller with primary side regulation. The device can control the output voltage and current by sensing auxiliary winding voltage. CXAC85173 operates in pulse width modulation mode (PWM) or pulse frequency modulation mode (PFM) automatically to keep the conversion efficiency high across the line ranges. The ECXAC85173contains thermal shutdown function, over-voltage protection and over-current protection.
•<30mW 的空载功耗
•±5%的恒压恒流调整精度
•PSR架构无需光耦
•超低启动电流
