EVAL-STCH03-45W
EVAL BOARD, QR FLYBACK CONTROLLER
- Manufacturer:
- STMICROELECTRONICS STMICROELECTRONICS

- Order Code:
- 3387308
- Technical Datasheet:
- EVAL-STCH03-45W Datasheet
Product Overview
45W/12V isolated power supply 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. The protections are auto-restart for a safe operation.
- Input voltage range (VIN) from 90VAC to 265VAC
- Output range from 12V to 3.75A continuous operation
- Very low stand-by power of less than 40mW at 230Vin
- Average full load efficiency of 88% at 115VIN, 89% at 230VIN
- Active mode at 10% load efficiency 84% at 115VIN, 82% at 230VIN
- Active mode at 10% load efficiency > 84% at 115VIN > 82% at 230VIN
- Safety according to EN60065, EMI according to EN55022 Class B
- Small PCB form factor of 85mm x 55mm x 25mm
