ESCRIPTIONS
The 4000HN, single output power modules are 25 to 40 watt
DC/DC converters available in a single output configuration
providing 3.3 VDC to 15 VDC outputs in a compact, industry
standard 2" X 2" X 0.5" package. These 400kHz, switching
converters are available in 12, 24 and 48 VDC inputs making
them one of the most versatile product lines in the market
with efficiencies up to 89%. Advanced surface mount
construction allows these converters to achieve outstand-
ing thermal performance eliminating the need for thermal
potting compounds and thereby enhancing manufacturing
efficiency to reduce costs.

The converter’s output voltage may be trimmed by up to
±10%
of the nominal output voltage.
TRIM UP
Trim output voltage up by connecting an external resistor between Pins 8 and 9. Use the following equation,
reference Table 1 for variables A and B.
Radj-up =
A
Δ
%
- B (kΩ)
Example:
Trim 5% up for 12V Output units,
where A = 1.58, B = 15,
