The Power Integrations INN2003K-TL is an isolated Flyback offline switcher from the InnoSwitch™-CH series featuring secondary-side synchronous rectification. It integrates the power switch with a 650V breakdown rating and delivers up to 12W at 100kHz switching frequency with a 60% maximum duty cycle. Protection includes current limiting, over temperature, and over voltage. It is housed in a 15-lead 16-PowerSOIC package and rated from -40°C to 85°C.
- Isolated Flyback topology with secondary-side SR supports efficient, galvanically isolated designs.
- Integrated switch with 650V breakdown simplifies the power stage and reduces external parts.
- 100kHz switching frequency and 60% max duty cycle enable compact magnetics.
- Current limiting, over temperature, and over voltage protection enhance reliability.
- 15-lead 16-PowerSOIC package suits space-constrained isolated supplies.
