2.1 Power Requirements

Follow these steps to set up the power supply:

  1. Connect 5.5V power supply to the power jack (PWR_JACK) connector (J19) of the TRF-LSC-AFE7950EVM.
  2. Check that the D9 (PWR) LED light is on. The power supply draws approximately 550mA to 650mA.
  3. Connect a USB type mini-B cable from the PC to the USB port (J20) of the TRF-LSC-AFE7950EVM.
  4. Check that the D10 (USB_PWR) LED light is on. The LED light strength depends on the USB cable length. If the LED light is not on, then use a shorter USB cable. TI tested a three-foot USB cable in this setup.
  5. The power-supply sequencer on the TRF-LSC-AFE7950EVM has a power status for each rail. If the power good (PGOOD) is logic high, then the corresponding power supply rail is powered correctly. The respective LED lights is on. Check that the following LEDs lights are on.
    • D5 (1P8) LED
    • D6 (1P2) LED
    • D7 (0p9) LED
    • D8 (3p3_LMK) LED
