The Power Integrations INN4077C-H181-TL is an offline flyback switcher from the InnoSwitch™4-CZ series rated at 135 W for 85-265 VAC input. It integrates a 750 V switch and provides galvanically isolated conversion with secondary-side synchronous rectification, operating from 50 kHz to 140 kHz. Current limiting, over load, over temperature, over voltage, short circuit, and UVLO protection, plus frequency control and soft start, support reliable operation from -40°C to 105°C in a compact 24-PowerSMD module.
- 135 W output with an integrated 750 V switch for high power density.
- Galvanically isolated flyback with secondary-side SR for efficient conversion.
- Comprehensive protection: current limiting, over load, over temperature, over voltage, short circuit, and UVLO.
- Wide 50 kHz to 140 kHz frequency range with frequency control and soft start.
- -40°C to 105°C operating range for demanding environments.
