Description: High Precision CC/CV Primary-Side PWM Power Switch

Features

* including Cycle-by-Cycle current limiting, VDD OVP, VDD clamp and UVLO. Excellent EMI performance is achieved with On-Bright proprietary frequency shuffling technique. High precision constant voltage (CV) and constant current (CC) can be achieved by LT1548. FEATURES

Applications

* It operates in primary-side sensing and regulation. Consequently, opto-coupler and TL431 could be eliminated. Proprietary Constant Voltage (CV) and Constant Current (CC) control is integrated as shown in the figure below. In CC control, the current and output power setting can be adjusted externall
