5 TPS65313-EVM Power-Up and Power-Down Procedure

The EVM is preconfigured with the default jumper settings listed in Table 2. Follow these steps to power up the device:

  1. Connect the input supply voltage between the VBAT and PGND connectors to supply the TPS65313-Q1 device.
  2. Press the S2 switch to apply a wake-up pulse which starts the device power up.
  3. It is possible to power up the device using the WAKE button on the GUI, when the J20 jumper is connected between pins 2 and 3, and the EVM is connected to the computer. Before activating the WAKE button on the GUI, click the Re-Initialize USB2ANY button on the GUI to establish communication between the EVM and the GUI. For more information regarding GUI functionality, see Section 6.

The TPS65313-EVM does not require any special power-down sequence. The EVM can be powered down by turning off the VBAT supply or clicking the CLR_WAKE_LATCH button on the GUI.
