Working Principles

The MP2482DN-LF is a step-down converter that utilizes pulse-width modulation (PWM) to regulate the output voltage. It operates by switching the input voltage on and off at a high frequency, which is then filtered and smoothed to provide a stable output voltage. The feedback pin monitors the output voltage and adjusts the duty cycle of the switching signal to maintain the desired output voltage.
