The Power Integrations INN4275C-H181-TL is an isolated offline flyback switcher featuring secondary-side synchronous rectification and up to 100 W output. It integrates the internal switch with a 750 V breakdown rating and operates at 50 kHz to 140 kHz. Protection includes current limiting, over temperature, over voltage, and UVLO, plus soft start control. The 24-PowerSMD module operates from -40°C to 105°C.
- Isolated flyback topology with secondary-side SR for efficient, safe offline conversion.
- 750 V breakdown voltage for robust mains-connected designs.
- Integrated switch reduces external components and simplifies design.
- Fault protection (current limiting, OVP, OTP, UVLO) improves reliability.
- Wide -40°C to 105°C range for demanding applications.
