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
in
requirements from 9 to 75 Volts.
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.
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
out
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 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).

an external 0.47µF multi-layer ceramic capacitor installed across their output pins.
Nominal line voltage, no-load/full-load conditions.
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

Options and Adaptations
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 48V
in
) 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.
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 (1.2-5V
out
), ±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.

information.
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, 48V

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.

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 applica-
tion 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.
