LT1548 High Precision CC/CV Primary-Side PWM Power Switch

LT1548 Description

LT1548 High Precision CC/CV Primary-Side PWM Power Switch GENERAL .
LT1548 is a high performance offline PWM Power switch for low power AC/DC charger and adaptor applications.

LT1548 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

LT1548 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
