The Power Integrations INN4072C-H181-TL is an isolated flyback AC-DC converter with secondary-side synchronous rectification, delivering 50 W from an 85-265 VAC input. It integrates the power switch rated at 750 V breakdown and operates from 50 kHz to 140 kHz with frequency control and soft start. Comprehensive protections include current limiting, over load, over temperature, over voltage, short circuit, and UVLO across a -40°C to 105°C range.
- Integrated 750 V switch simplifies isolated flyback design and reduces external component count.
- Secondary-side SR improves efficiency in a 50 W flyback topology.
- Wide 50 kHz to 140 kHz frequency control with soft start eases EMI and inrush management.
- Comprehensive fault protection (OCP, OLP, OTP, OVP, SCP, UVLO) enhances reliability.
- -40°C to 105°C operating range supports demanding environments.
