Product Details

Demonstration circuit SCP-LT3483-EVALZ is an inverting converter featuring the LT3483ES6. The converter generates –15V at 8mA to 40mA from a 2.7–12V input using a dual coupled inductor in an inverting flyback topology.

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-1X5BKOUT-EVALZ
SCP-THRUBRD-EVALZ

SCP-FILTER-EVALZ
SCP-1X2BKOUT-EVALZ
SCP-5X1-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 the Demo Manual does not cover details important to the operation and configuration regarding the LT3483 buck regulator. Please refer to the LT3483 data sheet for a complete description of the part.
