The Power Integrations INN2105K-TL is an offline flyback switcher from the InnoSwitch™-CE series with an integrated power switch and 650V breakdown voltage. It delivers up to 20W at 100kHz with a 60% maximum duty cycle, using flyback topology with secondary-side synchronous rectification and galvanically isolated output. The 16-PowerSOIC device includes over-temperature and over-voltage protection across a -40°C to 105°C ambient range.
- Integrated switch and secondary-side SR simplify isolated flyback designs.
- 650V breakdown voltage supports offline AC input designs.
- 100kHz switching and 60% max duty cycle enable compact power stages.
- Over-temperature and over-voltage protection improve reliability.
Isolated AC-DC Adapters
The INN2105K-TL supports flyback designs up to 20W with a 650V breakdown rating and 60% max duty cycle for isolated adapters.
