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.

QPS100P changing output voltage

The output voltage -Vout is given by the formula:

-Vout = - R × 400 µA

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