Working Principles

The MP2104DJ-LF-Z is a step-down switching regulator that converts a higher input voltage to a lower output voltage. It utilizes a pulse-width modulation (PWM) control scheme to regulate the output voltage. The internal MOSFET switches on and off at a high frequency, allowing efficient power conversion. The feedback pin (FB) monitors the output voltage and adjusts the duty cycle of the internal switch to maintain a stable output.
