The Power Integrations INN3949CQ-TL is an isolated flyback offline switcher from the InnoSwitch™3-AQ series with an integrated switch and a 1700V breakdown rating. It delivers up to 70W, operates from a 30V to 1000V Vcc supply with a 30V start-up voltage, and switches from 25kHz to 95kHz. Protections include current limiting, over temperature, over voltage, and short circuit. It is housed in a 24-PowerSMD module package.
- 1700V breakdown rating supports high-voltage offline rails with wide safety margin.
- 70W output power suits medium-power isolated flyback designs.
- Wide 30V to 1000V Vcc supply range with 30V start-up enables robust wide-input operation.
- Integrated switch and 25kHz to 95kHz frequency range simplify isolated converter design.
- Comprehensive protection and -40°C to 125°C range improve reliability in demanding environments.
