Product Details

The LinkSwitch-3 family of ICs 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.

The device incorporates a 725 V power MOSFET, a novel ON/OFF control state machine, a high-voltage switched current source for self biasing, frequency jittering, cycle-by-cycle current limit and hysteretic thermal shutdown circuitry onto a monolithic IC.

Product Highlights

Dramatically Simplifies CV/CC Converters

Eliminates optocoupler and all secondary CV/CC control circuitry
Eliminates all control loop compensation circuitry

Advanced Performance Features

Compensates for transformer inductance tolerances, input line voltage variations, and cable voltage drop
