DATEL’s BMP Models are fully potted, 25-40 Watt, dual-output DC/DC converters designed to meet UL1950 and EN60950-1 safety standards. The
combination the BMP’s higher efficiencies and thermally conductive potting compound enables these devices to achieve higher operating temperatures
without derating. The 2" x 3" BMP "footprint" conforms to the standard pinout
and pin geometries of most 3" x 3" devices (a 33% space savings) while
delivering 60% more power (40W vs. 25W).
Applicable to a wide range of telecom, computer and other OEM applications,
BMP Model DC/DC’s offer ±5V, ±12V and ±15V outputs. They operate from four
different input voltage ranges with total available output being a function of the
selected range. "Q12" models operate from 10-36V and deliver 25W. "Q48" models
operate from 18-75V and deliver 30W. For "D24" and "D48" models, the input
ranges and output powers are 18-36V at 35W and 36-75V at 40W, respectively.
These devices employ corrosion-resistant metal cases with plastic headers.
Heat-generating transformer cores and power semiconductors are mounted directly
to the cases, which have threaded inserts for optional add-on heat sinks or pcb
mounting. Temperature derating information is provided for operation with and without heat sinks and forced air flow.
All devices feature input pi filters, input overvoltage shutdown, output overvoltage protection, output current limiting, and thermal shutdown. UL, CSA, EN and IEC
compliance testing is currently in progress (75V-input devices will be CE marked) as
are full EMI/EMC characterizations. Contact DATEL for the latest available information.

As shown below, BMP Model DC/DC Converters are classified by output
power. For dual-output devices, the total output power from the two outputs
can not exceed the rated power. For example, "Q48" models have a maximum output power of 30W. Therefore, if the +Output is sourcing 20 Watts,
the –Output is limited to sourcing 10 Watts ensuring the total output power
does not exceed 30 Watts.

➀ These converters require a minimum 10% loading on each output to maintain
specified regulation. Operation under no-load conditions will not damage these devices;
however they may not meet all listed specifications.
➁ "Full load" varies by part number and is determined by the input voltage range as indi
cated by the part number suffix. See Technical Notes and Output Power Considerations.
➂ Application-specific input/output filtering can be recommended or perhaps added inter
nally upon request. Contact DATEL Applications Engineering for details.
➃ Applying a voltage to the On/Off Control pin when no input power is applied to the con
verter can cause permanent damage to the converter.
➄ Listed specification is for input-to-output isolation. Input-to-case and output-to-case
isolation is 1000Vdc, minimum.

TECHNICAL NOTES
Floating Outputs
Since these are isolated DC/DC converters, their outputs are "floating." Any
BMP model may be configured to produce an output of 10V, 24V or 30V (for
±5V, ±12V or ±15V models, respectively) by applying the load across the
+Output and –Output (pins 9 and 6), with either output grounded. The Common (pin 8) should be left open. Minimum 20% loading is recommended
under these conditions. The total output voltage span may be externally
trimmed as described below.
Filtering and Noise Reduction
All BMP 25-40 Watt DC/DC Converters achieve their rated ripple and noise
specifications without the use of external input/output capacitors. In critical applications, input/output ripple and noise may be further reduced by
installing electrolytic capacitors across the input terminals and/or low-ESR
tantalum or electrolytic capacitors across the output terminals. Output
capacitors should be connected between their respective output pin (pin 6 or
9) and Common (pin 8). See Figure 7. The caps should be located as close
to the converters as possible. Typical values are listed in the below. In many
applications, using values greater than those listed will yield better results.

Output Power
BMP Model, dual-output DC/DC converters incorporate a design tradeoff between total available output power and input voltage range. The total available
power is a function of both the nominal input voltage and the "width" of the
input voltage range. For a given nominal input (24V or 48V), narrower ranges
(2:1 vs. 4:1) have more available power. For a given "width" of input range
(2:1 or 4:1), higher nominal inputs (48V vs. 24V) have more available power.
Each device, as indicated by its part-number suffix (Q12, Q48, D24 or D48)
has a total output power limitation of 25, 30, 35 or 40 Watts, respectively.
Observing these power limitations is the user's responsibility.
As indicated by its Part Number Structure, each ±5V, ±12V or ±15V BMP
device is capable of sourcing up to ±4, ±1.65 or ±1.3 Amps, respectively.
Users have the flexibility of loading either output up to these limits; however
you must be extremely careful not to exceed the total output power rating of
any given device. If, for example, a ±5V device with a 30W power rating
(BMP-5/4-Q48) is sourcing 4A from its +5V output (representing 20W of
+Output power), that device can only supply an additional 10W (2 Amps)
from its –Output.
As a consequence of this "power-allocation" flexibility, the definition of "full
load," as the condition under which performance specifications are tested
and listed, is ambiguous. The following table lists the positive and negative
output currents that DATEL uses to define each device’s "full load."
Threaded Inserts and Heatsink Installation
CAUTION: Do not use the threaded inserts to bolt the converter down to a
PC board. That will place unnecessary force on the mounting pins. Instead,
the converter is held securely by only soldering the mounting pins.
When attaching the heat sink from above the converter, use a maximum
torque of 2 inch-pounds (0.23 N-m) on the 4-40 bolts to avoid damaging the
threaded inserts. Use a tiny amount of fastener adhesive or 4-40 lockwashers
to secure the bolts.
Soldering Guidelines
Murata Power Solutions recommends the specifications below when installing these converters. These specifications vary depending on the solder type. Exceeding these
specifications may cause damage to the product. Be cautious when there is high atmospheric humidity. We strongly recommend a mild pre-bake (100° C. for 30 minutes). Your
production environment may differ; therefore please thoroughly review these guidelines with your process engineers.
