The TLV320AIC1106EVM-K motherboard (the USB-MODEVM Interface board) supplies power to J5 of
the TLV320AIC1106EVM. Power for the motherboard is supplied either through its USB connection or via
terminal blocks on that board.

4.1
Stand-Alone Operation
When used as a stand-alone EVM, power can be applied directly to J5. The user must be 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
product data sheet before applying power to the EVM.

USB-MODEVM Interface Power
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 V to 10 Vdc, either through the J8 terminal block or the 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.

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.
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 lights when the power supplies are active.
