QPS100N User Guide

Quick start

1. Connect the load on the output connector.
2. Supply the board from -7 V to -5.5 V, nom. -6 V.

Changing the output voltage

Output voltage can be set between -2 V and -15 V by removing the resistor at B and adding either a resistor R at C or a trimming potentiometer at A.

The output voltage -V_out is given by the formula:

-V_out = - R × 400 µA

Input supply voltage must be kept between -V_out - 0.5 V and -V_out - 2 V (V_out - 1 V recommended).
