OUTPUT VOLTꢀGE ꢀDJUSTMENT (1600 DUꢀL)
The converter’s output voltage may be trimmed by up to ±10% of the nominal output voltage.
TRIM UP (Case ꢀ)
Trim output voltage up by connecting an external resistor between Pins 5 and 6. Use the following equation,
reference Table 1 for variable ꢀ.
ꢀ
Δ %
- 24 (ꢁΩ)
Radj-up =
Example:
Trim 5% up for 12V Output units,
where ꢀ = 2.23, Δ % = 0.05

0.05
RꢀDJ-UP
- 24 (ꢁΩ) = 20.6 ꢁΩ
Radj-up =
Both outputs are trimmed up by 5%.

TRIM DOWN (Case ꢀ)
Trim output voltage down by connecting an external resistor between Pins 5 and 8. Use the following
equation, reference Table 2 for variables C and D.
