Constant voltage switching regulator for adapters and chargers
LinkSwitch-CV
Power Integrations
Energy Efficient, CV or CV/CC Switcher for
Very Low Cost Adapters and Chargers
Cost Effective Linear/RCC Replacement
* Lowest cost and component count, constant voltage (CV)
or constant voltage/constant current (CV/CC) solution
* Extremely simple circuit configuration
* Up to 75% lighter power supply reduces shipping cost
* Primary based CV/CC solution eliminates 10 to 20 secondary
components for low system cost
* Combined primary clamp, feedback, IC supply, and loop
compensation functions - minimizes external components
* Fully integrated auto-restart for short circuit and open loop
fault protection - saves external component costs
* 42 kHz operation simplifies EMI filter design
Much Higher Performance Over Linear/RCC
* Universal input range allows worldwide operation
* Up to 70% reduction in power dissipation - reduces enclosure
size significantly
* CV/CC output characteristic without secondary feedback
* System level thermal and current limit protection
* Meets all single point failure requirements with only one
additional clamp capacitor
* Controlled current in CC region provides inherent soft-start
* Optional opto feedback improves output voltage accuracy
