3 Getting Started

Figure 3-1 illustrates the TPS541620DEVM-050 EVM. The EVM is provided with input/output connectors and test points as shown inTable 4-1. A power supply capable of supplying 4 A or greater must be connected to J1 and/or J3 through a pair of wires 20AWG or lower. The Vout load must be connected to J2 and/or J4 through a pair of wires 20 AWG or lower. The maximum load current capability output is 12 A. Wire lengths should be minimized to reduce losses in the wires. The VIN input voltage can be monitored using TP3 with TP5 as the ground reference or using TP4 with TP6 as the ground reference. TP1 is used to monitor the output voltage VOUT with TP24 as the ground reference.

Make sure jumpers J9 and J10 are set in the ON position which enables both the DC/DC converters on the TPS541620. Jumper J9 enables DC/DC1 of the TPS541620. Setting the jumpers to the OFF position will disable the DC/DC converter. Apply the input voltage supply of 12 V to J1 and/or J3. Connect your oscilloscope or multimeter probes to the appropriate test points to observe.
