QUICK START PROCEDURE
Demonstration circuit 1194A is easy to set up to evalu-
ate the performance of the LTM8020. Refer to Figure 4
for proper measurement equipment setup and follow the
procedure below:
NOTE: Do not hot-plug the V
voltage. The absolute maximum voltage on V
and hot-plugging a power supply through wire leads to
the demonstration circuit can cause the voltage on the
extremely low ESR ceramic input capacitor to ring to
twice its DC value. In order to protect the IC, a higher
ESR aluminum electrolytic capacitor is placed at the input
terminals. This may protect against some, but not all, input
transients due to hot-plugging with a power supply. See
Application Note 88 for more details.
