InnoSwitch3-EP
Power Integrations' off-line CV/CC QR flyback switcher IC integrates a primary-side switch, synchronous rectification, and FluxLink™ feedback
Power Integrations' InnoSwitch3-EP family of ICs dramatically simplifies the design and manufacture of flyback power converters, particularly those requiring high efficiency and/or compact size. The InnoSwitch3-EP family incorporates a high-voltage power switch, primary and secondary controllers, and safety-rated feedback into a single IC. These devices integrate multiple protection features including line overvoltage and undervoltage protection, output overvoltage and overcurrent limiting, and overtemperature shutdown. Devices are available with standard and peak power delivery options, as well as commonly used auto-restart protection behaviors.
Features
- Very high efficiency across the full load range
- Power Integrations' proprietary gallium nitride technology
- Adjustable accurate output current sense using an external output sense resistor
- Exceptional CV/CC accuracy, independent of external components
- Integrated FluxLink, hipot-isolated, feedback link
- Up to 100 W output without heatsinks
- Up to 1700 V breakdown voltage
