Description
This evaluation board can output a voltage of 35 V isolated from an input of 90 Vac to 264 Vac, and the maximum output current is 1.2 A.The one-converter flyback type achieves a high power factor (PF > 0.9). The control IC uses BD7693FJ,which use the critical mode. Switching loss and noise are reduced by zero current detection. A circuit that lowers total harmonic distortion (THD) us used to support IEC610003-2 Class C and Class D.
Features
- Boundary Conduction Mode PFC
- Low THD Circuit Incorparation
- VCC Under Voltage Lock Out Function
- ZCD by Auxiliary Winding
- Static OVP by The VS Pin
- Error Amplifier Input Short Protection
- Stable MOSFET Gate Driving
- Soft Start Function
Typical applications
- Lighting Equipment, AC Adopter, TV, Refrigerator, etc
