The Power Integrations INN4274C-H181-TL is an isolated offline flyback switcher with secondary-side synchronous rectification, delivering up to 90 W. It integrates the switch with a 750V breakdown rating and operates from an 85V ~ 265V Vcc supply across a 50kHz ~ 140kHz switching frequency range. Protections include current limiting, over temperature, over voltage, and UVLO, with soft start control. Housed in a 24-PowerSMD module, it is rated for -40°C ~ 105°C (TA).
- Integrated switch with 750V breakdown rating simplifies isolated flyback designs and reduces external component count.
- Secondary-side SR topology improves efficiency in isolated offline supplies up to 90 W.
- Comprehensive protection suite (current limiting, OVP, OTP, UVLO) enhances reliability.
- Wide -40°C ~ 105°C operating range supports demanding thermal environments.
- Soft start control limits inrush stress during startup.
