The Power Integrations INN2004K-TL, part of the InnoSwitch™-CH series, is an isolated flyback switcher with secondary-side synchronous rectification and an integrated 650V switch. It delivers up to 15W at 100kHz switching frequency with 60% maximum duty cycle, and includes current limiting, over temperature, and over voltage protection. It is rated for -40°C to 85°C ambient in a 16-PowerSOIC (15-lead) package.
- Secondary-side synchronous rectification topology supports accurate isolated regulation.
- Integrated 650V switch reduces external component count and board space.
- 15W output at 100kHz switching frequency enables compact, efficient flyback designs.
- Current limiting, over temperature, and over voltage protection improve safety.
- 16-PowerSOIC package with 15 leads suits space-constrained power stages.
Low-Power USB Chargers
The INN2004K-TL delivers up to 15W in an isolated flyback with secondary-side synchronous rectification, making it well suited to compact USB chargers. Its 650V integrated switch and 100kHz switching frequency support small, efficient transformer designs.
Consumer Electronics Adapters
For set-top boxes and networking gear, the InnoSwitch-CH series device provides isolated offline conversion with 60% maximum duty cycle. Over temperature and over voltage protection help maintain safe operation across -40°C to 85°C ambient.
Auxiliary Bias Supplies
Secondary-side SR improves cross-regulation in multi-output bias designs. The integrated 650V switch and current limiting protection simplify isolated auxiliary rails in appliances and industrial boards.
IoT and Smart Home Power
Compact 16-PowerSOIC packaging and integrated switch make the INN2004K-TL a fit for space-limited smart home devices needing a galvanically isolated 15W rail.
