Other Power Supplies
The AM571x IDK EVM contains 8 other power conversion devices that support the interface and memory
circuitry:
•
TPS63010 Buck-Boost Converter: This converter generates 5.0V from the main supply input. It
supplies this voltage to the industrial interface circuits, the HDMI interface and to the USB master
ports.
•
TPS61085 Boost Converter: This converter generates 12.0V from the main supply input. It supplies
voltage to the industrial interface circuits and the PCIe card connector.
•
TPS51200 DDR Termination Voltage LDO (2 each): This LDO provides the push/pull termination
current required for the DDR3 memory interfaces. There is one implemented for each DDR3 EMIF.
•
LP38693ADJ Low-Dropout Regulator: This LDO generates the 3.7V LCD bias voltage.
•
TPS61081DRC LCD Backlight Generator: This Boost converter generates the LCD backlight supply.
•
TPS71712 Low-Dropout Regulator: This LDO generates the 1.2V supply needed for the LCD driver
logic.
•
TPS76650 Low-Dropout Regulator: This LDO generates the 5.0V supply needed for the Profibus
interface.
•
R1Z-3.305HP Isolated DC-DC Supply: This converter generates 5.0V isolated from the primary
3.3V DC supply on board for the DCAN interface.
