Disadvantages: - Limited maximum continuous current (3A) - Requires external resistor for output voltage setting

Working Principles

The TPS2331IDRG4 load switch operates by controlling the flow of power from the input voltage source to the load. When the EN pin is high, the load switch is turned on, allowing current to flow from the input to the output. Conversely, when the EN pin is low, the load switch is turned off, cutting off the power supply to the load.

The FB pin is used to set the desired output voltage by connecting an external resistor. The PG pin provides a signal indicating whether the output voltage is within the specified range.
