Working Principles

The NCP3063BDR2G is a step-down switching voltage regulator that operates based on the principle of pulse width modulation (PWM). It converts the input voltage to a lower, regulated output voltage by rapidly switching the internal power MOSFET. This switching action controls the duty cycle and frequency of the output waveform, resulting in the desired output voltage. The feedback mechanism continuously monitors the output voltage and adjusts the duty cycle accordingly to maintain a stable output.
