*Note: Not all model number combinations may be available. Contact MPS.

Optional Functions

The A-Series 7-15W DC/DC Converters offer numerous electrical/ mechanical

options. Per the Ordering Guide on page 2, the trailing "A" (A-Series) in each

part number pertains to the base part number. Part-number suffixes are added

after the "A," 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. As described below, selecting certain options

will result in the installation of additional pins in certain locations.

Description

No Vout Trim or On/Off Control functions added (no I/O pins

installed in the pin 3 and pin 5 positions). The pin length remains at

0.2 inches (5.08 mm).

Add a Vout Trim function on pin 5. No pin 3 installed.

Add an On/Off Control function on pin 3 (with positive polarity). No

pin 5 installed.

Add the On/Off Control function (with positive polarity) on pin 3 and

add the Vout trim function on pin 5.

Add an On/Off Control function on pin 3 with negative polarity. No

pin 5 installed.

Add the On/Off Control function with negative polarity on pin 3 and

add the Vout trim function on pin 5.

Trim the pin length to 0.110 ±0.010 inches (2.79 ±0.25mm). This

option requires a minimum order quantity.

Single Output, High-Density,

6 Amp/15 Watt DC/DC Converters

L2

Trim the pin length to 0.145 ±0.010 inches (3.68 ±0.25mm). This

option requires a minimum order quantity.

-C

RoHS-6 hazardous substance compliance (does not claim EU RoHS

exemption 7b, lead in solder).

* Note: Usage of consecutive "C" and "-C" designations is correct for some

models. Example: UWR-5/3000-D48AC-C

Adaptations

There are various additional configurations available on A-Series 7-15W DC/DCs.

Because designating each of them with a standard part-number suffix would

result in an unmanageable matrix of part numbers, such are designated by

MPS and assigned 5-digit "part-number suffixes.

UWR-3.3/4250-D48AT-30690

Standard product, 48VIN, 3.3VOUT/4.25A with a VOUT Trim function added in

the pin 3 position, with adapted current limit set point to 6.5A min. and with

removed Input Overvoltage Shutdown function.

UWR-5/3000-D48ACT-30770

UWR-5/3000-D48ACT-30770-Y (RoHS-5)

Standard product, 48VIN, 5VOUT/3A. On/Off Control function (positive polarity)

on pin 3, VOUT, Trim function added on pin 5. Adaptations: Trim equations are

Tyco/Lucent-compatible. Transformer isolation system has been enhanced to

meet the basic insulation requirements of UL60950-1/EN60950-1. I/O pins

are 25-mil-square Tyco/Lucent compatible. Shielded metal case is connected

to +VIN pin 1. Input Overvoltage Shutdown function has been removed.

UWR-3.3/4500-D48ANT

Standard UWR-3.3/4250-D48A, 48VIN, 3.3VOUT with slightly higher output

current (4.5A), negative on/off polarity control and a special competitive-

compatible trim.

UWR-3.3/4500-D48ANT accepts trim adjustments to ±10% of nominal VOUT

not to exceed 15W of maximum output power. Users should carefully consider

the amount of trim added since excessive positive trim may exceed the

overvoltage protection. Excessive negative trim may interfere with proper

regulation.

UWR-3.3/4500-D48ANST Special trim version. See page 5.

UWR-5/3000-D48ANSTHL2-Y

UWR-3.3/4500-D48ANTHL2-Y

Negative on/off polarity, special trim, conformal coating added, 3.68mm pin

length, RoHS-5 compliance (with lead). RoHS-5 compliance requires a sched-

uled quantity order. Not all RoHS-5 “-Y” models are available. Please contact

Product Marketing for further information.
