This section describes the jumpers and connectors on the EVM as well as how to properly connect, set
up, and use the TPS6505xEVM-195.
up, and use the TPS6505xEVM-195.
This is the positive input voltage connection to the converter. The EVM operates from any supply voltage
between 2.5 V and 6 V. The leads to the input supply should be twisted and kept as short as possible to
minimize EMI transmission and input voltage droop.

minimize EMI transmission and input voltage droop.
This is the input return connection for the input power supply.
This is the positive output for VDCDC1 step-down converter. This output is externally adjustable for the
TPS65050, TPS65051, and TPS65054. The output for the TPS65052 and TPS65056 is fixed. The EVM
preset output voltages are found in
TPS65050, TPS65051, and TPS65054. The output for the TPS65052 and TPS65056 is fixed. The EVM
preset output voltages are found in
. VDCDC1 is capable of sourcing up to 600 mA for the
TPS65050 and TPS65054 and up to 1 A for the TPS65051, TPS65052 and TPS65056.
This is the return connection for the VDCDC1 output rail.
This is the positive output for VDCDC2 step-down converter. This output is externally adjustable for the
TPS65050 and TPS65051. The output for the TPS65052, TPS65054 and TPS65056 is programmed by
the DEFDCDC2 input to two factory-programmed voltages. The EVM preset output voltages are found in
TPS65050 and TPS65051. The output for the TPS65052, TPS65054 and TPS65056 is programmed by
the DEFDCDC2 input to two factory-programmed voltages. The EVM preset output voltages are found in
. VDCDC2 is capable of sourcing up to 600 mA for all versions.
This is the return connection for the VDCDC2 output rail.
This is the positive output for the VLDO1 LDO linear regulator. This output is input programmable for the
TPS65050 and TPS65052 and externally adjustable for the TPS65051, TPS65054 and TPS65056. The
VLDO1 output is capable of supplying up to 400 mA. The EVM preset output voltages are found in
TPS65050 and TPS65052 and externally adjustable for the TPS65051, TPS65054 and TPS65056. The
VLDO1 output is capable of supplying up to 400 mA. The EVM preset output voltages are found in
.
