FB

Feedback input. OUT is preset to – 4.1V when FB is

grounded. OUT may be adjusted to other voltages by

connecting a resistor divider as shown in Figure 4.

CONT

Control input. VOUT is adjusted with a positive control

voltage (0V to 10V) applied to this input through a resistive

divider (Figure 5).
