The Power Integrations LNK3772D-H003-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. Current Limiting, Over Temperature, Over Voltage, Short Circuit, and UVLO 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.
- Comprehensive protection set including Current Limiting, Over Temperature, Over Voltage, Short Circuit, and UVLO.
- Frequency control at 66kHz supports stable switching behavior.
- 16-SOIC package rated for -40°C to 105°C ambient operation.
