Working Principle

The NMP1K2-###C#C-00 series AC/DC converters utilizes a high frequency, variation of the buck regulator topology to provide a very efficient conversion path from AC to DC. The converter consists of a synchronous rectifier bridge, a voltage regulator, a constant current source, and an output voltage feedback loop.

The AC input is rectified and then converted into a DC voltage by the bridge rectifier. The DC voltage is then filtered, and then passed into the voltage regulator. The voltage regulator is responsible for regulating the output voltage.

The constant current source is used to ensure that the output current is always at the desired value. The output voltage feedback loop is used to maintain the output voltage. When the output voltage begins to exceed the set point, the voltage regulator will reduce the output voltage by reducing the incoming current from the bridge rectifier.

The output voltage is adjusted by the voltage regulator to maintain the desired voltage. The output voltage is monitored by the voltage feedback loop to ensure that it is within the required limits. The constant current source ensures that the output current is kept to the desired value.
