SLVU579A December 2011 – September 2021 TPS54427
Table 4-1 shows the input/output connectors and test points of the TPS54427 evaluation module. Connect a power supply capable of supplying 2 A to J1 through a pair of 20 AWG wires. Connect the load to J2 through a pair of 20 AWG wires. The maximum load current capability is 4 A. Minimize wire lengths to reduce losses in the wires. Test point TP1 provides a place to monitor the input voltage, VIN, with TP2 providing a convenient ground reference. Use TP8 to monitor the output voltage, VOUT with TP9 as the ground reference.
| REFERENCE DESIGNATOR | FUNCTION |
|---|---|
| J1 | VIN (See Table 1-1 for VIN range.) |
| J2 | VOUT, 1.05 V at 4 A maximum |
| JP1 | EN control. Connect EN to OFF to disable, connect EN to ON to enable |
| TP1 | VIN test point at VIN connector |
| TP2 | GND test point at VIN |
| TP3 | EN test point. |
| TP4 | Loop response measurement test point |
| TP5 | VREG5 test point |
| TP6 | Switch node test point |
| TP7 | Analog ground test point |
| TP8 | Output voltage test point |
| TP9 | Ground test point at output connector |
