2.1 Power Supply Setup

The steps for setting up the power supply are as follows:

  1. Connect 5.5-V power supply to the power jack (PWR_JACK) connector (J19) of the TRF1208-AFE7950-EVM. The 5.5-V supply may be dropped to 5 V if power cable loss is not significant in the setup.
  2. Check the D9 (PWR) LED. It should be lit up. The power supply should draw about 550 mA to 650 mA.
  3. Connect a USB Type Mini-B Cable from the PC to the USB port (J20) of the TRF1208-AFE7950-EVM.
  4. Check the D10 (USB_PWR) LED. It should be lit up. The LED light may be weak depending on the USB cable length. If the LED is not lit up, then use a shorter USB cable. TI tested a three foot long USB cable in this setup.
  5. The power supply sequencer on the TRF1208-AFE7950-EVM has power status for each rail. If the power good (PGOOD) is in logic HI, then the corresponding power supply rail is powered correctly. The respective LED will light up. Check the following LEDs to see if they are lit.
    • D5 (1P8) LED
    • D6 (1P2) LED
    • D7 (0p9) LED
    • D8 (3p3_LMK) LED
