5.2 Recommended Test Setup
Figure 3 is the recommended test set up to evaluate the CSD86330EVM-717. Working at an ESD
workstation, make sure that any wrist straps, bootstraps or mats are connected referencing the user to
earth ground before power is applied to the EVM.
Figure 3. CSD86330EVM-717 Recommended Test Set Up
Input Connections:
• Prior to connecting the DC input source V
IN
, it is advisable to limit the source current from V
IN
to 10 A
maximum. Make sure V
IN
is initially set to 0 V and connected as shown in Figure 3.
• Connect a voltmeter V1 at TP1(V
IN
) and TP2(GND) to measure the input voltage.
• Connect a current meter A1 to measure the input current.
Output Connections:
• Connect load to VOUT1 and set load to constant resistance mode to sink 0 A
DC
before V
IN
is applied.
• Connect a voltmeter V2 at TP5 (V
OUT
) and TP6 (GND) to measure the output voltage.
Other Connections: Place a fan as shown in Figure 3 and turn on, making sure air is flowing across the
EVM.
