UHE Series

www.murata-ps.com

Isolated, High Efﬁciency, 1.6" × 2"

2-10 Amp, 12-30 Watt DC/DC Converters

Typical units

Housed in smaller, 1.6" x 2" x 0.40" (41 x 51 x 10.2mm)

packages carrying the standard 2" x 2" pinout, MPS’s new

UHE Series DC/DC Converters deliver more current/power

(up to 10A/30W) than currently available from either

package size.

FEATURES

PRODUCT OVERVIEW

The UHE 12-30W Series of high-efﬁciency,

isolated DC/DC’s provide output power ranging

from 10 Amps @ 1.2V to 2 Amps @ 15V. Offering

both 2:1 and 4:1 input voltage ranges, UHE’s meet

V^INrequirements from 9 to 75 Volts.

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.

All UHE models incorporate a V^OUTTrim function

and an On/Off Control pin (positive or negative

logic). Low-voltage models (1.2V to 5V) offer

optional sense pins facilitating either remote load

regulation or current sharing for true N+1 redun-

dancy. All models are certiﬁed to the BASIC insula-

tion requirements of UL/EN60950-1 (2nd Edition),

and 48V^IN(75V max.) models carry the CE mark.

Selected models are RoHS compliant (Reduction

of Hazardous Substances).

ꢀOutput conﬁgurations:

1.2/1.5/1.8/2.5V^OUT@ 10 Amps

3.3/5VOUT @ 25 Watts

Taking full advantage of the synchronous-

rectiﬁer, forward topology, UHEs boast outstanding

efﬁciency (some models exceed 91%) enabling

full-power operation to ambient temperatures as

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

fully automated, SMT-on-pcb techniques, UHEs

provide stable no-load operation, excellent line

( 0.1%) and load ( 0.15%) regulation, quick step

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

(50-100mVp-p). Additionally, the UHEs unique

output design eliminates one of the topology’s few

shortcomings–output reverse conduction.
