The Power Integrations INN4373F-H341-TL is an isolated flyback offline switcher from the InnoSwitch™4-Pro series featuring secondary-side synchronous rectification and an integrated 750V power switch. It delivers up to 75W and switches between 90kHz and 110kHz. Control features include enable, frequency control, and soft start, with protections covering current limiting, over load, over temperature, over voltage, short circuit, and UVLO. It is housed in a 28-PowerSMD module and rated for -40°C to 105°C.
- Integrated 750V switch and secondary-side SR simplify isolated flyback design.
- Supports up to 75W output for adapter and embedded supply applications.
- Broad protection suite including short circuit, over voltage, over load, and over temperature.
- Frequency control and enable features provide flexible operation.
- Compact 28-PowerSMD module package enables space-efficient layouts.
High-Efficiency Isolated Adapters
The InnoSwitch4-Pro flyback architecture with secondary-side synchronous rectification and a 750V integrated switch supports efficient isolated power conversion at up to 75W for compact adapters.
USB-PD and Fast-Charging Power Supplies
