Circuit Principle:

The TPS57060QDGQRQ1 is a Buck Converter (DC-DC step-down converter) designed for power supply applications requiring high efficiency. The device operates by switching a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) rapidly on and off, filtering the resulting high-frequency signal with inductors and capacitor s to produce a smooth DC output voltage. The converter dynamically adjusts the duty cycle of the switch to regulate the output voltage based on feedback from the output (via the FB pin) to maintain stable operation.
