LinkSwitch Family

     

LinkSwitch-3 dramatically simplifies low power CV/CC charger designs by eliminating an optocoupler and secondary control circuitry. The device introduces a revolutionary control technique to provide very accurate output voltage and current regulation, compensating for transformer and internal parameter tolerances along with input voltage variations.


 

LinkSwitch-PH – simplifies offline LED designs requiring flicker-free dimming, high power factor, and high efficiency. LinkSwitch-PH also introduces a control technique that provides active power factor correction, accurate constant current output and primary side control.


 

LinkSwitch-II dramatically simplifies low power CV/CC charger designs by eliminating an optocoupler and secondary control circuitry. The device introduces a control technique to provide tight output voltage and current regulation, compensating for transformer and internal parameter tolerances and input voltage variations.

 

LinkSwitch-HP incorporates a primary side regulated (PSR) controller and high-voltage power MOSFET in a single package. The IC family includes devices optimized for constant voltage (CV) operation at power ranges from 9W to 90 W.
