EVM Setup
This section describes how to properly connect and setup the TPS746EVM-009, including the jumpers
and connectors on the EVM board.
2.1
Input/Output Connector and Jumper Descriptions
2.1.1
J1 – IN
Input power-supply voltage connector. Twist together the positive input lead and ground return lead from
the input power supply, and keep them as short as possible to minimize input inductance.
2.1.2
J2 – OUT
Regulated output voltage connector.
2.1.3
J3 – VPU
Pullup-voltage selector for PG. This EVM is designed so that PG can be pulled up either to VOUT by
shorting J3, or pulled up to another voltage by applying an external voltage to the VPU post.
2.1.4
J4 – IN_S
Input sense.
2.1.5
J5 – OUT_S
Output sense.
2.1.6
J6 – ENABLE
Output enable. To enable the output, connect a jumper to short IN to EN. To disable the output, connect a
jumper between GND and EN
2.1.7
J7 – GND
Input ground return connector.
2.1.8
J8 – GND
Output ground return connector.
2.1.9
J9 – OUTPUT VOLTAGE Set
For convenience, the EVM is prepopulated with four resistor divider options. Place a shunt on J9 next to
the silkscreen label of your desired output voltage.
2.1.10
TP1 – IN_S
Input sense test point.
2.1.11
TP2 – OUT_S
Output sense test point.
2.1.12
TP3 – EN
Enable test point.
