Low Power Off-Line Digital PWM AC/DC Controller CXAC85185 is a high performance offline PWM controller for low power AC/DC charger and adaptor applications. It operates in primary-side regulation

   产品概述 返回TOP7iu嘉泰姆

     CXAC85185 is a high performance offline PWM controller for low power AC/DC charger and adaptor applications. It operates in primary-side regulation. Consequently, opto-coupler and voltage reference IC such as CXPU3357D could be eliminated. Proprietary Constant Voltage (CV) and Constant Current(CC) control are integrated. In CC control, the current and output power setting can be adjusted externally by the sense resistor Rs at CS pin. In CV control, multi-mode operations are utilized to achieve high performance and high efficiency. In addition, good load regulation is achieved by the built-in wireloss compensation. CXAC85185 offers power-on soft-start control and protection coverage with auto-recovery features including Cycle-by Cycle current limiting, VCC UVLO,OTP, SCP. Excellent EMI performance is achieved with frequency shuffling technique.   CXAC85185 is available in SOT23-6 packages.
