Working Principles

The LNK362PG utilizes primary-side control technology to regulate the output voltage. It operates by sensing the feedback voltage through the FB pin and adjusting the duty cycle of the internal power switch accordingly. This control mechanism eliminates the need for an optocoupler or secondary-side feedback circuitry, reducing cost and complexity.

The integrated circuit incorporates various protection features such as over-temperature, over-voltage, and short-circuit protection to ensure safe operation under different conditions. In case of a fault, the auto-restart protection feature activates, allowing the device to resume normal operation once the fault is removed.
