Working Principle

The MP4560DN-LF switching regulator works by generating a high frequency pulse width modulated (PWM) voltage output. The switching frequency of the regulator is set by an external resistor and can be adjusted to optimize performance in specific applications. The main components of the regulator are a power MOSFET, an inductor, and a diode.

The power MOSFET is used to control the current flow, and is turned on and off according to the voltage input. The current flows through the inductor and the power MOSFET is turned off, which generates a voltage spike. This voltage spike is then rectified by the diode to produce a steady output voltage.

The output voltage is regulated by the switching frequency. The regulator uses the voltage feedback signal to adjust the switching frequency, making sure that the output voltage remains constant. The MP4560DN-LF also offers over temperature and over current protection, as well as an adjustable soft start feature and on/off delays.
