The Power Integrations INN4376F-H341-TL is a 125W offline flyback switcher from the InnoSwitch™4-Pro series. It integrates the power switch with a 750V breakdown rating and delivers galvanically isolated output via secondary-side synchronous rectification. Operating from an 85V to 265VAC input with EN, frequency control, and soft start, it includes current limiting, over load, over temperature, over voltage, short circuit, and UVLO protection across -40°C to 105°C in a 28-PowerSMD module.
- 125W power rating supports mid-power isolated flyback designs.
- Integrated 750V switch and secondary-side SR simplify architecture.
- Comprehensive fault protection improves reliability.
- Wide -40°C to 105°C range supports demanding environments.
- EN, frequency control, and soft start enable flexible tuning.
Mid-Power Adapters and Chargers
The 125W rating and integrated 750V switch support isolated flyback designs for mid-power adapters and chargers.
Industrial Power Supplies
Secondary-side SR flyback topology with comprehensive fault protection (current limiting, over load, OVP, OTP, SCP, UVLO) suits industrial offline supplies.
Appliance Power Boards
Wide -40°C to 105°C range and robust protection support reliable appliance power conversion.
Networking Equipment
Galvanically isolated flyback output with EN, frequency control, and soft start supports isolated offline power for networking gear.
