DESCRIPTION
Demonstration circuit SCP-LT3483-EVALZ is an inverting
converter featuring the LT3483ES6. The converter gener-
ates –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

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
LT3483
buck regulator. Please refer to the

  • Page 2: Quick Start Procedure

    Refer to Figure 2 and follow these steps: put voltage, make sure the load is initially set to zero. 1. The SCP-LT3483-EVALZ ships with a default output 3. Check for proper output voltage. The output should be voltage of –15V. To change the output voltage, see regulated at the programmed value (±5%).

    0510650300 with crimp pin 50212-8000. The output of the SCP-LT3483-EVALZ is resistor-program- To use an active run signal, use a 1.00M resistor for either mable from –1V to –39V. The board can be also configured pull-up or pull-down resistors R5 and R6, short R4 with to drive VIOC-capable linear regulators.
