Typical unit  
ꢀ„  
Low profile 0.4" height with 0.9" x 2.3"  
outline dimensions  
For efficient, fully isolated DC power in the smallest space, the UCE  
open frame DC-DC converter series fit in industry-standard “eighth  
brick” outline dimensions and mounting pins (on quarter-brick pinout).

PRODUCT OVERVIEW  
ꢀ„  
Outstanding thermal performance  
and derating  
Units are offered with fixed output voltages from  
1.5 to 12 Volts and currents up to 30 Amps. UCEs  
operate over a wide temperature range (up to +85  
degrees Celsius at moderate airflow) with full rated  
power. Interleaved synchronous rectifier topology  
yields excellent efficiency over 90% and no reverse  
output conduction.  
UCEs achieve these impressive mechanical and  
environmental specs while delivering excellent  
electrical performance in a through-hole package.  
Overall noise is typically 50 mV pk-pk (low voltage  
models) with fast step response. These converters  
offer tight output regulation and high stability even  
with no load. 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.  
“Hiccup” output protection automatically restarts  
the converter when the fault is removed.  
ꢀ„  
Extensive self-protection and short  
circuit features with no output reverse  
conduction  
A convenient remote On/Off control input enables  
phased startup and shutdown in multi-voltage ap-  
plications. To compensate for longer wiring and to  
retain output voltage accuracy at the load, UCEs em-  
ploy a Sense input to dynamically correct for ohmic  
losses. A trim input may be connected to a user’s  
adjustment potentiometer or trim resistors for output  
voltage calibration. The UCE will tolerate substantial  
capacitive loading for bypass-cap applications.  
UCEs include industry-standard safety certifica-  
tions and BASIC I/O insulation provides input/output  
isolation to 2250V. Radiation emission testing is  
performed to widely-accepted EMC standards.
