Quasi-resonant GaN flyback reference design
PMP31406
概覽
This reference design generates a 24V output with 2.5A load current from a 195VAC to 265VAC input. This design uses the self-biasing gallium nitride (GaN) flyback UCG28826. This design can deliver 60W output power. The design does not need an auxiliary transformer winding because this device has a self- bias and auxless sensing scheme integrated. The design operates at 130kHz switching frequency for full load and reduces switching frequency for medium or light load to keep efficiency high.
特點
- Aux-less sensing eliminates the need for an auxiliary winding
- Switching frequency less than 130kHz
- Output: 24V at 2.5A
- Integrated GaN FET with quasi-resonant operation
