Typical unit
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
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.
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.
