Working Principles

The LNK624PG utilizes a primary-side control technique, where the control circuitry is powered directly from the input voltage. This eliminates the need for an optocoupler and secondary-side feedback components, simplifying the design and reducing cost.

The IC operates by regulating the duty cycle of the internal power MOSFET based on the feedback received from the FB pin. This ensures a stable output voltage regardless of variations in input voltage and load conditions.

In case of fault conditions such as over-temperature or short-circuit, the auto-restart protection feature shuts down the IC temporarily and automatically restarts it once the fault condition is removed.
