Programming Voltage Common to the Minus Output

Figure 4

The output will always be the same or less than the programming voltage.

The M/S2 switch must be in the down position. For best results, place a 0.1μF capacitor in parallel with R2.

Vin = (R1R2) / R2 x Vout

Vout = R2 / R1+R2) x Vin

Where Vout is the power supply output voltage. Vin is the programming voltage.

R1 and R2 should be in the 1KΩ to 100KΩ range.
