2.4 Power Supply

VDUT supplies power to the TMP4719 device, and must be set between 1.62V to 5.5V for normal operation of the TMP4719EVM. The mechanical switch SW2 is used to connect VDUT to the subregulator output (3P3V) or external supply (VEXT).

VDUT is default connected to the on-board subregulator U7, which regulates USB power down to 3.3V. When using an external supply voltage, the user can connect the external power supply using the VEXT and GND test points, or by soldering headers or wires on the breakout section. The green LED D2 lights up when VDUT is supplied properly.
