For efficient, fully isolated DC power in the smallest space, the UEE
ope
open frame DC-DC converter series fit in industry-standard “eighth
bri
brick” outline dimensions and mounting pins (on quarter-brick pinout)
or surface mount option.
PRODUCT OVERVIEW
Units are offered with a fixed output voltage and
current up to 45 Amps. UEEs operate over a wide
temperature range (up to +85 degrees Celsius at
moderate airflow) with full rated power. Synchro-
nous rectifier topology yields excellent efficiency.
UEEs achieve these impressive mechanical and
environmental specs while delivering excellent
electrical performance in an industry standard
DOSA compatible through-hole package or surface
mount option. The unit is fully protected against
input undervoltage, output overcurrent and short
circuit. An on-board temperature sensor shuts
down the converter if thermal limits are reached
and automatically restarts the converter when the
fault is removed.
An On/Off control input enables phased startup
and shutdown in multi-voltage applications. UEEs
include a Sense input to correct for ohmic losses. A
trim input may be connected to a user’s adjustment
potentiometer or trim resistors for output voltage
calibration.
UEEs include industry-standard safety certifi-
cations and BASIC I/O insulation provides input/
output isolation to 2250V. Radiation and conducted
emission testing is performed to widely accepted
EMC standards.

All specifications are typical unless noted. General conditions for Specifications are +25 deg.C,
Vin=nominal, Vout=nominal (no trim installed), full rated load. Adequate airflow must be supplied
for extended testing under power.
All models are tested and specified with external 1μF and 10 μF paralleled output capacitors and
no external input capacitor. All capacitors are low ESR types. Caps are layout dependent. These
capacitors are necessary to accommodate our test equipment and may not be required in your
applications. All models are stable and regulate within spec under no-load conditions.

Notes
➀
Unless otherwise noted, all specifications are at nominal input voltage, nominal output voltage and
full load.
General conditions are +25˚ Celsius ambient temperature, near sea level altitude, natural convec-
tion airflow.
All models are tested and specified with external parallel 1 μF and 10 μF multi-layer ceramic
output capacitors.
A 220μF external input capacitor is used. All capacitors are low-ESR types wired close to the
converter.
➁
Input (back) ripple current is tested and specified over 5 Hz to 20 MHz bandwidth. Input filtering is
Cbus=220 μF, Cin=33 μF and Lbus=12 μH.
➂
All models are stable and regulate to specification under no load.
➃
The Remote On/Off Control is referred to -Vin. For external transistor control, use open collector
logic or equivalent.
