UHE Series
www.murata-ps.com
Isolated, High Efficiency, 1.6" × 2"
2-10 Amp, 12-30 Watt DC/DC Converters
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.

PRODUCT OVERVIEW
n
The most IOUT/POUT in this format
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
Vin requirements from 9 to 75 Volts.
Taking full advantage of the synchronousrectifier, 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.

1500 Vdc I/O BASIC Insulation
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 Vout Trim 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 redundancy. All models are certified to the BASIC insulation requirements of UL/EN60950-1 (2nd Edition),
and 48Vin (75V max.) models carry the CE mark.
Selected models are RoHS compliant (Reduction
of Hazardous Substances).

Devices have no minimum-load requirements and will regulate under no-load conditions.
Regulation specifications describe the output voltage deviation as the line voltage or load
(with/without sense option) is varied from its nominal/midpoint value to either extreme.

Optional Functions and Part Number Suffixes
The versatile UHE, 12-30W DC/DC converters offer numerous electrical and
mechanical options. Per the Ordering Guide on page 2, the trailing DXX or QXX
(where XX stands for 12, 24 or 48Vin) in each part number pertains to the base
part number. Part-number suffixes are added after this input identification,
indicating the selection of standard options. The resulting part number is a
"standard product" and is available to any customer desiring that particular
combination of options.
T
Alternate trim configuration. Special order only.
-C
Full RoHS-6 compliance.
-Y
RoHS-5 hazardous substance compliance with lead exception. RoHS-5
compliance requires a scheduled quantity order. Not all RoHS-5 “-Y”
models are available. Please contact Product Marketing for further
information.
The On/Off Control function on pin 4 employs a positive logic (on = open or
"high," no suffix). To request a negative logic on this pin/function, add an "N"
suffix to the part number. Standard models have no pins in the pins 5 and 8
positions. For 5-10A models (1.2-5Vout), ±Sense pin/functions can be added to
these positions (see pinout P52) by adding an "R" suffix. An "NR" suffix can be
added for both negative-logic and sense-pin options. See below.
Suffix Description
Blank Positive logic On/Off Control function (pin 4), Vout trim (pin 9),
no Sense pins, pin length 0.2 inches (5.08 mm).
N
Add Negative logic on the On/Off Control function, VOUT trim (pin 9),
no Sense pins.
R
Positive logic on the On/Off Control function, Vout trim (pin 9), ±Sense
pins in the pin 5 and pin 8 positions (available for low Vout models
only). Available under special order.
NR
Negative logic on the On/Off Control function, Vout trim (pin 9), +/–
Sense pins in the pin 5 and pin 8 positions (available for low Vout
models only). Available under special order.
Adaptations
There are various additional configurations available on UHE, 12-30W DC/DCs.
Because designating each of them with a standard part-number suffix is not
always feasible, such are designated by MPS in assigning a 5-digit “adaptation
code” after the part-number suffixes. Contact MPS directly if you are interested
in your own set of options/adaptations. Our policy for minimum order quantities
may apply. Consequently, the following products are offered for sale:
UHE-5/6000-D48N-30749
UHE-5/6000-D48N-30749-Y (RoHS-5)
Standard product, 48Vin, 5V/6A output with negative logic on the On/Off Control
function, modified Trim function (5% trim up = 9.09kΩ, 5% trim down =
3.83kΩ, compatible with UEP-30750), integrated soft start and with input OVP
and thermal shutdown removed.
RoHS-5 compliance refers to the exclusion of the six hazardous substances
in the RoHS specification with the excepion of lead. MPS’s RoHS-5 products
use all the conforming RoHS materials, however our solders contain lead.
UHE-3.3/7500-D48THL2-Y and
UHE-5/6000-D48THL2-Y (RoHS-5)
Special trim, conformal coating, 3.68mm pin length, positive on/off logic,

➀ All models are tested and specified with a single, external, 0.47µF, multi-layer ceramic output
capacitor and no external input capacitors, unless otherwise noted. All models will effectively
regulate under no-load conditions (with perhaps a slight increase in output ripple/noise).
➁ See Technical Notes/Performance Curves for additional explanations and details.
➂ Input Ripple Current is tested/specified over a 5-20MHz bandwidth with an external 33µF input
capacitor and a simulated source impedance of 220µF and 12µH. See I/O Filtering, Input Ripple
Current and Output Noise for details.
➃ The On/Off Control is designed to be driven with open-collector (or equivalent) logic or the application of appropriate voltages (referenced to –Input (pin 2)). Applying a voltage to the On/Off Control
pin when no input voltage is applied to the converter can cause permanent damage. See Remote
On/Off Control for more details.
➄ Extreme Accuracy refers to the accuracy of either trimmed or untrimmed output voltages over all
normal operating ranges and combinations of input voltage, output load and temperature.
➅ Tie the Output Trim pin (pin 9) to +Output (pin 6) for maximum trim down or to –Output (Output
Return/Common, pin 7) for maximum trim up. See Output Trimming for detailed trim equations.
➆ The Current-Limit-Inception point is the output current level at which the converter's power-limiting
circuitry drops the output voltage 2% from its initial value. See Output Current Limiting and
Short-Circuit Protection for more details.
➇ For Start-Up-Time specifications, output settling time is defined as the output voltage having
reached ±1% of its final value at maximum load current.
➈ MTBF’s are calculated using TELCORDIA SR-332 Method 1 Case, ground fixed, +25°C ambient air
and full-load conditions. Contact MPS for demonstrated life-test data.
➉ All models are fully operational and meet all published specifications, including "cold start," at –40°C.
Use only as much output filtering as needed and no more. Larger caps (especially low-ESR ceramic
types) may slow transient response or degrade dynamic performance. Thoroughly test your system
with all components installed.

Input Undervoltage Shutdown and Start-Up Threshold
Under normal start-up conditions, devices will not begin to regulate until
the ramping-up input voltage exceeds the Start-Up Threshold Voltage. Once
operating, devices will not turn off until the input voltage drops below the
Undervoltage Shutdown limit. Subsequent re-start will not occur until the input
is brought back up to the Start-Up Threshold. This built in hysteresis prevents
any unstable on/off situations from occurring at a single input voltage.
