2.1 Input and Output Connections

The TPS54332EVM-416 is provided with input and 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 J4 through a pair of 20 AWG wires. The maximum load current capability must be 3.5 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.

Table 2-1 EVM Connectors and Test Points
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, 2.5 V at 3.5 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
