The INN4777C-H190-TL from Power Integrations is an isolated flyback AC-DC converter with secondary side synchronous rectification. It integrates a 750V power switch and delivers up to 220 W across a 50kHz to 140kHz switching frequency range. The 24-PowerSMD module includes current limiting, over temperature, over voltage, and UVLO protection with soft start, rated for -40°C to 105°C operation.
- Secondary side SR flyback topology improves rectification efficiency in isolated designs.
- 220 W output power supports high-power AC-DC applications.
- Integrated 750V switch reduces external component count.
- Wide 50kHz–140kHz frequency range offers design flexibility.
- UVLO, OTP, OVP, and current limiting protections enhance reliability.
