Working Principle

The DPD090100-P14N AC/DC desktop and wall adapters use high frequency switching technology, also known as the “flyback” topology. This topology relies on a power transistor to control the output voltage and current. The input voltage is rectified and filtered to generate a DC voltage. This voltage is monitored by the primary control loop. Depending on the load, the power transistor is either turned on or off via a feedback loop.

During the on-cycle, the DC input voltage is switched to the secondary side of the transformer via the power transistor. The secondary coil of the transformer produces an AC voltage, which is rectified and filtered to generate a regulated output voltage. The output voltage is monitored and regulated by the feedback loop, which is adjusted to maintain the desired output voltage. During the off-cycle, the power transistor is off and the energy stored in the transformer’s secondary coil is released. This process repeats continuously and is regulated by the feedback loop to ensure a stable output voltage.
