LNK603 Description
The LinkSwitch™-II 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 tight output voltage and current regulation, pensating for transformer and internal parameter tolerances along with input voltage variations. The device incorporates a 700 V power MOSFET, a novel ON/OFF...
