Working Principles

The MIC4826BMM is a synchronous buck regulator that uses pulse-width modulation (PWM) to regulate the output voltage. It operates by switching the input voltage on and off at a high frequency using an internal MOSFET. This switched voltage is then filtered and regulated to provide a stable output voltage.

The regulator adjusts the duty cycle of the switching signal based on the feedback received from the FB pin. This feedback loop ensures that the output voltage remains constant even with changes in load or input voltage.
