Working Principles

The TPS62260DDCT is a step-down (buck) voltage regulator. It operates by converting a higher input voltage to a lower, regulated output voltage. This is achieved through the use of an inductor, capacitor, and a control circuit that switches the inductor on and off at high frequency. The switching action transfers energy from the input to the output, resulting in the desired voltage regulation.
