CR623X is a high performance offline PWM power switch for low power AC/DC charger and adaptor applications. It operates in primary-side sensing and provides constant voltage (CV) and constant current (CC) regulation without TL431 and opto-coupler. A typical output CC/CV curve is shown as in the Fig.1. Fig.1. Typical CC/CV Curve Control with Primary Side Fee.
Up to 5% Precision for Constant Voltage Regulation and Constant Current Regulation at Universal AC input Primary-side Sensing and Regulation Without TL431 and Opto-coupler Flyback Topology In DCM Operation Soft-start Built-in Leading Edge Blanking (LEB) Frequency Jitter to Reduce System EMI Programmable CV and CC Regulation Adjustable Constant Current and Output Power Setting Built-in Secondary Constant Current Applications Cell Phone /Digital Cameras Charger Small Power Adaptor General Description CR623X is a high performance offline PWM power switch for low power AC/DC charger and adaptor ap.
