Working Principles

The TPS53114PW is a synchronous buck converter, which means it converts a higher input voltage to a lower output voltage efficiently. It achieves this by using two power MOSFETs (high-side and low-side) that switch on and off alternately. When the high-side MOSFET is on, current flows from the input through an inductor to store energy. When the high-side MOSFET turns off, the stored energy is released to the output through the low-side MOSFET and the output capacitor. This switching action allows for efficient voltage conversion.
