DESCRIPTION
Demonstration circuit SCP-LT8609S-BEVALZ is a 42V,
2A/3A peak micropower synchronous step-down regula-
tor featuring the LT8609S. The demo board is configured
for a 5V output from a 5.5V to 42V input.
Like all boards in the Signal Chain Power series, this board
is designed to be easily plugged into other SCP boards to
form a complete signal chain power system, enabling fast
evaluation of low power signal chains. To evaluate this
board, some universal SCP hardware is required, namely:
SCP-INPUT-EVALZ
SCP-OUTPUT-EVALZ
SCP-FILTER-EVALZ
SCP-THRUBRD-EVALZ

To properly evaluate SCP series demo boards, you will
need the SCP Configurator companion software. SCP
Configurator can help you choose the right board and to-
pology for your design.
Note that this Demo Manual does not cover details im-
portant to the operation and configuration regarding the
LT8609S. Please refer to the
