6.1 Enable/Disable Switch S1

The TPS53015EVM-126 is equipped with a switch (S1) to drive the EN pin of the TPS53015. When S1 is in the Enable position, EN is connected to VIN, and the TPS53015 is enabled and generates a regulated 1.05-V output. When S1 is in the Disable position, EN is connected to GND, and the TPS53015 enters a high impedance output state.

Default setting: Set S1 to the Disabled position to disable the controller.
