Setup Instructions for the ISL6271A Evaluation Kit
DVM Testing
Monitor Vcore DC voltage (TP8-TP9), while varying the voltage set-point using the I2C commands from the drop-
down voltage palate on the PC screen. The variable slew rate command-set can be verified by monitoring Vcore at
TP5 with a scope set on AC coupling and 200mV/Div sensitivity. The scope could be set to one-shot trigger off the
change in Vcore voltage, commanded by the user adjusting the trigger level about 50mV from the ‘0’V level in the
commanded direction. A more reliable, and repeatable, one-shot trigger is the incoming I2C clock signal. This signal
can be easily accessed on either end of the red conductor in the I2C interconnect cable. Now, when the ‘Write I2C’
command is given, the scope will trigger on the clock burst, and the Vcore voltage slew rate to the new voltage level
can be observed. This is illustrated below in Figure 13 for both a positive and negative slew command.
