Test Setup
4.2 Recommended Test Setup
Figure 3. CSD87588NEVM-603 Recommended Test Setup
Figure 3 shows the recommended test setup to evaluate the CSD87588NEVM-603. Working at an ESD
workstation, make sure that any wrist straps, bootstraps, or mats are connected. Reference the user-to-
earth ground before power is applied to the EVM.
Input Connections:
1. Prior to connecting the DC source VIN, TI recommends to limit the source current from VIN to 10-A
maximum. Ensure that VIN is initially set to 0 V and connected (as shown in Figure 3 ).
2. Prior to connecting the DC source V5VIN, TI recommends to limit the source current from 5V to 0.5-A
maximum. Ensure that V5VIN is initially set to 0 V and connected (as shown in Figure 3 ).
3. Connect a voltmeter, V1, at TP304 (Vins) and TP305 (GNDS) to measure VIN voltage, V2 at TP301
(5V), and TP302 (GND) to measure 5V voltage (as shown in Figure 3 ).
4. Connect a current meter A1 between DC source VIN and J303 to measure the input current.
5. Connect a current meter A2 between DC source V5VIN and J301 to measure the 5V input current.
Output Connections:
1. Connect the load to J304 and set load to constant resistance mode to sink 0-ADC before VIN and
V5VIN are applied.
2. Connect a voltmeter V3 at TP308 (VOUTS) and TP309 (GNDS) to measure the output voltage.
