The INN4276C-H183-TL by Power Integrations is an isolated flyback offline switcher featuring an integrated 750V switch and secondary-side synchronous rectification. It delivers up to 125 W over a 50kHz to 140kHz switching range, with current limiting, over temperature, over voltage, and UVLO protection plus soft start. The 24-PowerSMD module operates from -40°C to 105°C.
- Integrated 750V switch reduces external component count and simplifies design.
- Secondary-side synchronous rectification supports efficient isolated conversion.
- 125 W output suits medium-power offline applications.
- Built-in current limiting, OTP, OVP, and UVLO improve reliability.
- Wide -40°C to 105°C range for demanding environments.
Medium-Power AC-DC Adapters
The 125 W rating and 750V integrated switch provide margin for universal mains offline adapters using a flyback topology.
Industrial and Embedded Supplies
Operating from -40°C to 105°C with over temperature and over voltage protection, it suits rugged embedded power designs.
Isolated Output Power Systems
Secondary-side synchronous rectification in a flyback configuration supports efficient isolated rails for downstream electronics.
