DESCRIPTION
Demonstration circuit SCP-LT8604C-BEVALZ is a high ef-
ficiency 42V, 120mA synchronous step-down regulator.
The wide input range also allows inversion if using the
SCP-LT8604C-IEVALZ-version.
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
LT8604C. Please refer to the
