SY50135中文资料With Primary Side CV/CC Control For Adapters and Chargers数据手册Silergy规格书

描述 Description

SY50135 is a single stage Flyback controller targeting at Constant Current/Constant Voltage (CC/CV) applications. It integrates a 600V MOSFET to decrease physical volume. Both the output current and voltage are sensed by primary side signal process. SY50135 operates quasi-resonant mode and adaptive PWM/PFM control for highest average efficiency. In addition, SY50135 has cable compensation to regulate the output voltage for better load regulation at cable terminal.
