SLVU263A August 2008 – October 2021 TPS54231
The TPS54231EVM-372 is provided with input/output connectors and test points as shown in Table 2-1. A power supply capable of supplying 2 A must be connected to J1 through a pair of 20 AWG wires. The load must be connected to J4 through a pair of 20 AWG wires. The maximum load current capability must be 2 A. Wire lengths must be minimized to reduce losses in the wires. Test-point TP1 provides a place to monitor the VIN input voltages with TP2 providing a convenient ground reference. TP5 is used to monitor the output voltage with TP6 as the ground reference.
| Reference Designator | Function |
|---|---|
| J1 | VIN (see Table 1-1 for VIN range) |
| J2 | 2-pin header for enable. Connect EN to ground to disable, open to enable. |
| J3 | 2-pin header for slow start monitor and GND. |
| J4 | VOUT, 3.3 V at 2 A maximum |
| TP1 | VIN test point at VIN connector |
| TP2 | GND test point at VIN |
| TP3 | PH test point |
| TP4 | Test point between voltage divider network and output. Used for loop response measurements. |
| TP5 | Output voltage test point at OUT connector |
| TP6 | GND test point at OUT connector |
