UCE Series

Isolated, High-Density, Eighth-Brick

100W DC/DC Converters

www.murata-ps.com

FEATURES

■

ꢀRoHS compliant

Typical unit

■

ꢀIndustry standard eighth-brick pinout

and package

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).

■

ꢀOutputs from 1.5V to 12V up to 100W

■

ꢀLow proﬁle 0.4" height with 0.9" x 2.3"

outline dimensions

■

ꢀ36 to 75 Vdc input range (48V nominal)

PRODUCT OVERVIEW

■

ꢀFully isolated, 2250 Vdc (BASIC)

insulation

Units are offered with ﬁxed output voltages from

1.5 to 12 Volts and currents up to 40 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.

UCE’s 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.

■

ꢀOutstanding thermal performance

and derating

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.

■

ꢀExtensive self-protection and short

circuit features with no output reverse

conduction

■

ꢀOn/Off control, trim and sense functions

■

ꢀInterleaved synchronous rectiﬁcation

yields high efﬁciency over 90%

■

ꢀFully protected against temperature and

voltage limits

■

ꢀDesigned to meet UL/EN/IEC 60950-1

and CAN/CSA C22.2 No. 60950-1 safety
