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 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.
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.
Alternate pin lengths are available under special order
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.
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,
RoHS-5 hazardous substance compliance (with lead).
