TLV320AIC3253EVM-K Setup and Installation
2.5.1
Stand-Alone Operation
When used as a stand-alone EVM, power is applied to P23/J23 directly, making sure to reference the
supplies to the appropriate grounds on that connector.

CAUTION
Verify that all power supplies are within the safe operating limits shown on the
before applying power to the EVM.
P23/J23 provides connection to the common power bus for the TLV320AIC3253EVM. Power is supplied

2.5.2
USB-MODEVM Operation
The USB-MODEVM Interface board can be powered from several different sources:
•
USB
•
6-Vdc to 10-Vdc AC/DC external wall supply (not included)
•
Laboratory power supply
When powered from the USB connection, JMP6 must have a shunt from pins 1–2 (this is the default
factory configuration). When powered from 6-Vdc to 10-Vdc power supply, either through the J8 terminal
block or J9 barrel jack, JMP6 must have a shunt installed on pins 2–3. If power is applied in any of these
ways, onboard regulators generate the required supply voltages, and no further power supplies are
necessary.

ways, onboard regulators generate the required supply voltages, and no further power supplies are

If laboratory supplies are used to provide the individual voltages required by the USB-MODEVM Interface,
JMP6 must have no shunt installed. Voltages are then applied to J2 (+5VA), J3 (+5VD), J4 (+1.8VD), and
J5 (+3.3VD). The +1.8VD and +3.3VD can also be generated on the board by the onboard regulators from
the +5VD supply; to enable this configuration, the switches on SW1 need to be set to enable the
regulators by placing them in the ON position (lower position, looking at the board with text reading right-
side up). If +1.8VD and +3.3VD are supplied externally, disable the onboard regulators by placing SW1
switches in the OFF position.

Each power supply voltage has an LED (D1-D7) that illuminates when the power supplies are active.
