Temperature Derating and Electrical Performance Curves
Output Power
BMP Model, dual-output DC/DC converters incorporate a design tradeoff be-
tween 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 sufx (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 exibility 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" exibility, the denition of "full
load," as the condition under which performance specications are tested
and listed, is ambiguous. The following table lists the positive and negative
output currents that DATEL uses to dene 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 specications below when installing these converters. These specications vary depending on the solder type. Exceeding these
specications 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.
