J2 to LOAD1: The connection between the source voltage (VIN) and J1 of TPS53114EVM-541 can carry

as much as 4 Adc of current. The minimum recommended wire size is AWG 16 with the total length of

wire less than 2 feet (1-foot input, 1-foot return).

5.1.6 Other

Fan: The TPS53114EVM-541 evaluation module includes components that can become hot to the touch

when operating. This evaluation module is not enclosed in order to allow probing of circuit nodes;

therefore, a small fan capable of 200–400 lfm is recommended to reduce component temperatures when

operating.

5.2 Equipment Setup

Figure 2 is the recommended basic test setup to evaluate the TPS53114EVM-541. Note that although the

return for J1 and JP2 is the same system ground, the connections must remain separate as shown in

Figure 2.

5.2.1 Procedure

1. When working at an ESD workstation, ensure that any wrist straps, bootstraps, or mats are connected

referencing the user to earth ground before power is applied to the EVM. Electrostatic smock and

safety glasses also must be worn.

2. Prior to connecting the dc input source, V

, it is advisable to limit the source current from V

to 1 A

maximum. Ensure that V

is set initially to 0 V and connected as shown in Figure 2.

3. Connect VIN to J1 ( Figure 2).

4. Connect ammeter A1 between VIN and J1 ( Figure 2).

5. Connect voltmeter V1 to TP1 and TP2( Figure 2).

6. Connect voltmeter V2 to TP3 and TP4 ( Figure 2).

7. Connect oscilloscope probes to desired test points per Table 2.

8. Position fan as shown in Figure 2 and turn it on, ensuring that the air blows directly across the

evaluation module.
