Method 1: External Trim Resistor
(continued)
whichever is lower. By connecting an external resistor across P4 and P2, Vo is adjusted to a lower value. Only small
reductions, 2%, in voltage are recommended, as adjustment to lower voltages tends to affect the loop compensation of the
module.
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 (for APC08x08 series). Please refer to Centauri datasheet.
Example:

(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.
