AUGUST 9, 2002 - REVISION 02
Full range adjustment (from 0.9V to 3.6V) can be obtained from a module with the lowest Vo setpoint (0.9Vo).
To adjust Vo to a higher value, please refer to
Figure 4. The required resistor value (Rt) can be
determined through Equation (1) where Vo is the
voltage on P2 before the adjustment and Vot is the
voltage of P2 after Rt is connected.

Be aware that the maximum Vo allowed is 3.6V. Please refer to Centauri datasheet.
Example:
Module version: APC08J03-9 (1.8 to 6.0Vin, 0.9Vo).
Requiring to adjust output voltage from Vo = 0.9V to Vot = 1.8V. Vref = 0.875V and R1 = 3.09k (from TABLE 1).
Based on Equation (1), Rt can be determined as 3.0k
.
To adjust Vo to a lower value, Rt should be connected between P4 and P2. Equation (2) provides the calculation for Rt.

Be aware that the minimum Vo is 0.9V.
Example
Module version: APC08F03-9 (4.0 to 6.Vin, 3.3Vo).
Requiring to adjust the output voltage from Vo = 3.3V to Vot = 3.3 (1-0.02) = 3.234V.
Vo = 3.3V, Vot = 3.234V, Vref = 0.875V, R2 = 1.13k (from TABLE 1).
Based on Equation (1), Rt can be determined as 111.9k
