Figure 3-1. TPS7B4255EVM-062 Turn-On
If desired, a current probe can be inserted in the EVM as illustrated in Figure 3-2 to measure the input and
output current. The slots were sized to fit most current probes, such as the LeCroy
™
AP015 or CP031 current
probes.
The board layout is designed such that the I
in
current probe slot does not detect any current that goes to the
TPS7B84-Q1 circuit or its peripherals during start up or during any other operational mode. Thus, the I
in
current
probe slot can be used to isolate and accurately measure current into the TPS7B4255-Q1 solution.
