3.7 VBAT Power Supply Options

VBAT supply to TAS2320 is powered by 5V connected to VBAT barrel jack J21.

J5 on the bottom side of the EVM can be used to select between 2 different sources for VBAT.

  • VIN (J21) is selected by default, which is the barrel jack supplied by 5V.
  • VBAT (J30) is an alternative banana jack that can be used to supply VBAT to TAS2320 - U1 only. Use this for current and efficiency measurements.
CAUTION: 5V must be connected to barrel jack J21 even if using J30 for VBAT connection to TAS2320. VIN (J21) is used to power other things in the EVM.
