2.6 Power Supply

VDUT supplies power to the TMP411 device and pullup voltage of the communication lines, and must be set between 2.7V to 5.5V for normal operation of the TMP411EVM. The on-board regulator U7 regulates USB power down to 3.3V. The user can also disable the sub-regulator to apply a different supply voltage. To use an external power supply, follow these instructions:

  1. Flip the switch S1 to disable the sub-regulator; the green LED D2 turns off
  2. Connect the external power supply using the VDUT and GND test points, or by soldering headers or wires on the breakout section
  3. Supply VDUT; the green LED D2 turns on
  4. Use the GUI as normal
