Quick start

  1. Connect the load on the output connector.
  2. Supply the board from 5.5 V to 7 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-5 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).
