The Power Integrations INN4577F-H342-TL is an offline flyback converter with secondary-side synchronous rectification, delivering up to 145 W from an 85-265 VAC input. It integrates a 750 V switch, operates with a Vcc supply of 85 V to 265 V, and provides galvanically isolated output. Packaged in a 28-PowerSMD module, it is rated for -40°C to 105°C and includes current limiting, over load, over temperature, over voltage, short circuit, and UVLO protection with EN, frequency control, and soft start.
- 145 W output in a compact 28-PowerSMD module.
- Galvanic isolation with secondary-side SR for efficient offline conversion.
- 750 V breakdown switch supports universal 85-265 VAC input.
- Comprehensive fault protection (OV, OL, OT, SC, UVLO) for reliability.
- Wide -40°C to 105°C range for demanding environments.
Medium-Power Offline Adapters
The 145 W rating and 750 V breakdown switch suit universal 85-265 VAC adapters requiring isolated output with secondary-side SR.
Industrial and Embedded Supplies
Operating from -40°C to 105°C, the device supports industrial power designs needing wide thermal tolerance.
Chargers and Power Delivery
Integrated switch and secondary-side SR reduce external parts while maintaining galvanic isolation for safety.
Appliance Power
Fault protection including over voltage, over load, and short circuit supports reliable offline operation.
