The Power Integrations LNK3771D-H006-TL is an isolated flyback offline switcher with secondary-side synchronous rectification, delivering up to 7 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 reduces external component count for compact 7 W supplies.
- Comprehensive protection set including Current Limiting, Over Temperature, Over Voltage, Short Circuit, and UVLO.
- Frequency control at 66kHz supports stable, predictable switching behavior.
- 16-SOIC package rated for -40°C to 105°C ambient operation.
Low-Power Isolated Adapters
At 7 W output with a 725V integrated switch, this flyback switcher suits compact isolated chargers and adapters where secondary-side SR improves rectification efficiency.
Standby and Bias Supplies
The 85V to 265V Vcc range and 66kHz switching frequency support universal-input bias rails in appliances and industrial systems.
