The Power Integrations INN3990CQ-TL is an automotive-grade, AEC-Q100 qualified isolated flyback AC-DC switcher with secondary-side synchronous rectification and an integrated power switch. It features a 900V breakdown rating, operates from a 40V to 650V Vcc supply, and delivers 85W at a 25kHz to 95kHz switching frequency. Frequency control and soft start are included, along with current limiting, over temperature, over voltage, short circuit, and UVLO protection across a -40°C to 125°C ambient range in a 24-PowerSMD module.
- 900V breakdown rating enables high-voltage offline and automotive designs.
- AEC-Q100 automotive qualification for vehicle power systems.
- Integrated switch and secondary-side SR reduce external components.
- Comprehensive protection including over temperature, over voltage, short circuit, and UVLO.
- -40°C to 125°C ambient range for harsh environments.
