Introduction
1.3 Power-Supply Requirements and Connections
Only one power supply is needed to power the VSYS domain of the PMIC. Apply 3.135 VDC to 5.25 VDC
to the J20 connector of the TPS659037EVM to supply power to the PMIC device. Four-wire sensing of the
input power supply is recommended and can be achieved through the middle two terminals of J20.
Power for the MSP430 and the two fixed voltage LDOs (3.3-V and 1.8-V outputs) is supplied through the
USB connection, as shown in
Figure 2 .
