EVALUATION BOARD
GENERAL DESCRIPTION
The ADP199 evaluation board (ADP199CB-EVALZ) is
used to demonstrate the functionality of the ADP199
high-side load switch.
Simple device measurements such as V
(RDS
), ground current, and shutdown current can be dem-
ON
onstrated with only a single voltage source, a voltage meter, a
current meter, and a load resistor.
Complete information about the ADP199 high-side load
switch is available in the ADP199 data sheet, which should
be consulted when using the ADP199CB-EVALZ.
