Working Principle

The MEF1S0305SP3C converts a DC input voltage into a DC output voltage with a higher voltage. This is achieved by switching a voltage step-up circuit, which draws current from the input and creates an oscillating voltage of a predetermined frequency. The oscillating voltage is then rectified to create the output voltage. This process is called “switched-mode power conversion” and is the basis of the MEF1S0305SP3C.

The device employs a synchronous rectification technique to minimize losses, thus increasing efficiency. It also includes built-in features such as soft-start, under-voltage lockout, frequency synchronization, and feed-forward compensation, which help ensure proper operation and reduce noise and EMI.
