Working Principle

The MP2562DS-LF-Z is a synchronous step-down switching regulator that operates using synchronous rectification and phase-shift control. It consists of an internal PWM controller, an internal high-side and low-side switch, an inductor, and capacitors. The device operates in a buck (step-down) regulating mode where voltage is converted from a higher value to a lower value.

The input voltage is applied to the switch and the switch is then turned on and off rapidly to produce an equivalent DC output voltage. As the input voltage is higher than the output voltage, current is drawn from the input, stored in the inductor, and then released back to the output when the switch is opened. The PWM controller then controls the energy transfer between the input and output for precise voltage regulation.

The switching frequency of the regulator can be adjusted via an external resistor and the current limit can be set via an external resistor. The device also features soft-start and cycle-by-cycle current-limit functions, which help to protect the regulator from high-inrush currents and excessive load current.
