LT1548 Datasheet (Longtium Microelectronics) - High Precision CC/CV Primary-Side PWM Power Switch

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

LT1548 is a high performance offline PWM Power switch for low power AC/DC charger and adaptor 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

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
