2.1 Getting Started

Only a power supply and the EVM are required to evaluate and test the TPS6522x default configuration under load conditions.

  1. Connect the proper jumpers. For the default jumper connections see Figure 2-1.
  2. Connect power to the EVM.
  3. Connect the EVM to the host PC through the USB. If the power is provided by the USB cable, apply the appropriate jumper connection to connect 3.3V with VCCA. Please refer to Table 2-5 for the correct connections.
  4. Launch the GUI and evaluate.

Terminal J9, labeled VCCA in Figure 2-1 can accept wire gauges up to 14 AWG. The voltage supplied must be within the input range of the device, 3 V to 5.5 V. The power supply providing the input to VCCA is required to supply 135% of the output power. Once power has been supplied to VCCA, the VCCA can be connected to the EN/PB/VSENSE pin by placing jumper in J33 to power up the rails. Please refer to Table 2-6 for the correct jumper connection.

Note:

External Power Supply or Power Accessory Requirements:

  • Nominal Output Voltage: 3.3 or 5 VDC
  • Maximum Output Current: 10 A
  • Efficiency Level V

TI recommends using an external power supply or power accessory which complies with applicable regional safety standards such as (by example) UL, CSA, VDE, CCC, PSE, etc

Note: To ensure proper functionality of the TPS6522x VCCA must be between 3 V and 5.5 V although the label next to terminal J9 states lowest voltage of 2.8 V.
