Description
- EVAL-STCH03-45W, 45W/12V Isolated Power Supply Evaluation Board developed for general purpose applications. The evaluation board implements a Quasi Resonant flyback converter based on the STCH03 controller with optocoupler feedback for voltage and primary side regulation for constant output current regulation. The secondary side rectification is based on the SRK1000B adaptive synchronous rectification controller. The efficiency of the application is very high over entire output power range thanks to the smart power management of the STCH03 and SRK1000B controllers, the STF10LN80K5 MDmesh K5 primary MOSFET and the STL90N10F7 Power MOSFET for the synchronous rectification. The evaluation board implements a robust output supply protected against output overvoltage, output undervoltage, output overpower and output short-circuit
