SY23433B Overview
Key Features
- SY23433B is a single stage Flyback regulator targeting at high input voltage applications
- It integrates 900V MOSFET to decrease physical volume
- Both the output current and voltage are sensed by primary side signal process
- SY23433B operates in quasi-resonant mode and adaptive PWM/PFM control for highest average efficiency
- In addition, SY23433B integrates fast internal HV start up circuit to minimize no-load loss and external components
