Working Principles

The LNK606PG utilizes primary-side regulation (PSR) technology to achieve accurate voltage control. It operates by sensing the output voltage through the feedback pin (FB) and adjusting the duty cycle of the internal power switch accordingly. This approach eliminates the need for an optocoupler or secondary-side feedback circuit, simplifying the overall design.

The integrated circuit also incorporates frequency jittering to reduce electromagnetic interference (EMI) emissions. By modulating the switching frequency slightly, the LNK606PG spreads the energy across a wider frequency spectrum, minimizing the peak emissions at any specific frequency.

In case of abnormal conditions such as over-temperature, over-voltage, or short-circuit, the LNK606PG features built-in protection mechanisms that automatically shut down the device to prevent damage to the system. Once the fault condition is resolved, the IC will restart operation automatically.
