SLVU157A March 2006 – October 2021 TPS5430 , TPS5431
The TPS5430EVM-173 and TPS5431EVM-173 are provided with input/output connectors and test points as shown in Table 2-1. A power supply capable of supplying 3 A must be connected to J1 through a pair of 20 AWG wires. The load must be connected to J3 through a pair of 20 AWG wires. The maximum load current capability should be 3 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. TP3 is used to monitor the output voltage with TP4 as the ground reference.
| Reference Designator | Function |
|---|---|
| J1 | VIN (see Table 1-1 for Vin range) |
| J2 | OUT, 5 V at 3 A maximum |
| JP1 | 2-pin header for enable. Connect EN to ground to disable, open to enable. |
| TP1 | VIN test point at VIN connector |
| TP2 | GND test point at VIN |
| TP3 | Output voltage test point at OUT connector |
| TP4 | GND test point at OUT connector |
| TP5 | Test point between voltage divider network and R3. Used for loop response measurements. |
| TP6 | PH test point |
