Working Principles

The TPS22925CNYPHT operates by controlling the flow of power from the input to the output based on the enable signal. When the enable pin is high, the load switch is turned on, allowing power to flow from the input to the output. Conversely, when the enable pin is low, the load switch is turned off, cutting off the power flow.

The feedback pin (FB) is used to control the output voltage level, ensuring it remains within the desired range. The power good (PG) and fault (FLT) indicators provide information about the status of the load switch, enabling system monitoring.
