DESCRIPTION
Demonstration circuit SCP-LT3461-EVALZ features the
LT3461 in a 12V output boost converter which operates
from an input voltage of 3V to 6V. The maximum output
current is 70mA when powered from a 5.0V input and
40mA when powered from a 3.3V 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
