The INN2123K-TL from Power Integrations (InnoSwitch™-CE series) is an isolated Flyback offline switcher with secondary-side synchronous rectification and an integrated 650V switch. It delivers up to 12 W at 100kHz switching frequency with a 60% maximum duty cycle. Protection includes over-temperature and over-voltage. It is offered in a 16-PowerSOIC package rated for -40°C to 105°C ambient temperatures.
- Integrated 650V switch and secondary-side SR reduce external components and simplify isolated designs.
- Isolated Flyback topology provides galvanic isolation for safety compliance.
- 100kHz switching supports compact 12 W power supplies.
- Over-temperature and over-voltage protection enhance reliability.
- 16-PowerSOIC package suits space-constrained designs.
