UHE Series

P O W E R E L E C T R O N I C S D I V I S I O N

Isolated, High Efﬁciency, ꢀ.6" x 2" 2-ꢀ0 Amp, ꢀ2-30 Watt DC/DC's

Housed in smaller, ꢀ.6" x 2" x 0.40" (4ꢀ x 5ꢀ x ꢀ0.2mm) packages

carrying the standard 2" x 2" pinout, C&D's new UHE Series DC/

DC Converters deliver more current/power (up to ꢀ0A/30W) than

currently available from either package size.

FEATURES

PRODUCT OVERVIEW

nꢀThe most IOUT/POUT in this format

nꢀLower priced than bricks

The UHE ꢀ2-30W Series of high-efﬁciency, isolated

DC/DC's provide output power ranging from ꢀ0

Amps @ ꢀ.2V to 2 Amps @ ꢀ5V. Offering both

2:ꢀ and 4:ꢀ input voltage ranges, UHE's meet V^IN

requirements from 9 to 75 Volts.

shortcomings–output reverse conduction.

All devices feature full I/O fault protection including:

input overvoltage and undervoltage shutdown,

precise output overvoltage protection (a rarity on

low-voltage outputs), output current limiting, short-

circuit protection, and thermal shutdown.

nꢀSmall ꢀ.6" x 2" x 0.4" plastic package with

standard 2" x 2" pinout

nꢀOutput conﬁgurations:

ꢀ.2/ꢀ.5/ꢀ.8/2.5V^OUT@ ꢀ0 Amps

3.3/5VOUT @ 25 Watts

Taking full advantage of the synchronous-recti-

ﬁer, forward topology, UHE's boast outstanding

efﬁciency (some models exceed 9ꢀ%) enabling

full-power operation to ambient temperatures as

high as +60°C, without air ﬂow. Assembled using

fully automated, SMT-on-pcb techniques, UHE's

provide stable no-load operation, excellent line

( 0.ꢀ%) and load ( 0.ꢀ5%) regulation, quick step

response (200µsec), and low output ripple/noise

(50-ꢀ00mVp-p). Additionally, the UHE's unique

output design eliminates one of the topology's few

All UHE models incorporate a VOUT Trim function and

an On/Off Control pin (positive or negative polarity).

Low-voltage models (ꢀ.2V to 5V) offer optional

sense pins facilitating either remote load regula-

tion or current sharing for true N+ꢀ redundancy.

All models are certiﬁed to the BASIC insulation

requirements of UL/EN60950, and 48VIN (75V max.)

models carry the CE mark. Selected models are

RoHS compliant (Reduction of Hazardous Sub-

stances).

5/ꢀ2/ꢀ5VOUT @ 30 Watts

nꢀFive input ranges from 9-75 Volts

nꢀEfﬁciencies as high as 9ꢀ.5%

nꢀStable no-load operation

nꢀOptional Sense pins for low VOUT

nꢀThermal shutdown, I/O protected

nꢀꢀ500 Vdc I/O BASIC Insulation

nꢀUL/EN60950 certiﬁed; CE marked for Q48
