Working Principles

The CDC421250RGET is a DC-DC regulator that utilizes pulse-width modulation (PWM) to convert the input voltage to a regulated output voltage. It employs a high-frequency switching transistor to control the energy transfer from the input to the output. The feedback mechanism continuously monitors the output voltage and adjusts the duty cycle of the switching transistor to maintain the desired output voltage.
