The Power Integrations LNK3772D-H004-TL is an isolated flyback offline switcher with secondary-side synchronous rectification, delivering up to 12 W. It integrates a 725V switch, operates at 66kHz with frequency control, and runs from an 85V to 265V Vcc supply. Over Temperature and Over Voltage protection are included, and the 16-SOIC 14-lead package is rated for -40°C to 105°C ambient temperatures.
- Secondary-side synchronous rectification improves rectification efficiency in isolated flyback designs.
- Integrated 725V switch supports compact 12 W isolated supplies.
- Over Temperature and Over Voltage protection improve system robustness.
- Frequency control at 66kHz supports stable switching behavior.
- 16-SOIC package rated for -40°C to 105°C ambient operation.
Isolated Adapters
At 12 W with a 725V integrated switch, this flyback switcher suits isolated adapters where secondary-side SR improves rectification efficiency.
Appliance Auxiliary Rails
