Working Principles

The MP2488DN-LF-Z is a synchronous step-down converter that uses pulse-width modulation (PWM) control to regulate the output voltage. It operates by switching the input voltage through an inductor and transferring energy to the output capacitor. The feedback pin monitors the output voltage and adjusts the duty cycle of the internal switches to maintain the desired voltage level. The soft-start function gradually ramps up the output voltage during startup to prevent excessive inrush current.
