PRODUCT OVERVIEW
For your moderate-power mixed-logic designs,
DATEL’s BMP-5/5-3.3/4-D24 (18-36V input) and
BMP-5/5-3.3/4-D48 (36-75V input) are fully iso-
lated DC/DC converters providing both 5V and 3.3V
outputs. Housed in DATEL’s standard 2" x 3" x 0.5"
metal packages, these BMP duals can simultane-
ously source up to 4.7 Amps from their 5V outputs
and up to 3.5 Amps from their 3.3V outputs.
tection, output overvoltage protection, output cur-
rent limiting, and thermal shutdown. Both outputs
are controlled via the On/Off Control function (pin
5). The 5 Volt output can be adjusted 5ꢀ.
BMP Model DC/DC’s deliver high efficiency

(82ꢀ) and are fully specified for –40 to +100°C
operation. Their corrosion-resistant metal cases
have non-conductive baseplates and threaded
inserts for easy heat-sink attachment and/or PCB
mounting. These devices satisfy IEC950, UL1950
Both outputs are fully isolated (1500Vdc) and
independently line ( 1.0ꢀ) and load ( 1.0ꢀ)
regulated. Both models feature input pi filters, input and EN60950 safety requirements for BASIC insula-
overvoltage shutdown, input reverse polarity pro-
tion. CE marking is available for "D48" models.

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 recom-
mend a mild pre-bake (100° C. for 30 minutes). Your production environment may differ; therefore
please thoroughly review these guidelines with your process engineers.

On/Off Control (Standard)
10k
The On/Off Control pin (pin 5) may be used for remote on/off operation. As
shown in Figure 6, the control pin has an internal 10kΩ pull-up resistor to
approximately 10V. The converter is designed so that it is enabled when the
control pin is left open (normal mode) and disabled when the control pin is
pulled low (to less than +1.2V relative to –Input, pin 2).

ON/OFF
CONTROL

–INPUT
Dynamic control of the on/off function is best accomplished with a mechani-
cal relay or an open-collector/open-drain drive circuit (optically isolated if
appropriate). The drive circuit should obviously be able to sink approximately
1.5mA when activated and withstand more than 10 Volts when deactivated.

Applying an external voltage to pin 5 when no input power is applied to the
converter can cause permanent damage to the converter. The on/off control
function, however, is designed such that the converter can be disabled (pin
5 pulled low) while input power is ramping up and then "released" once the
input has stabilized. Under these circumstances, it takes approximately 30ms
for the output of the fully loaded DC/DC to ramp up and settle to within 1ꢀ
of its fi nal value after the converter has been turned on.

Output Trimming
The total output voltage span of the 5 Volt output, from +5V Output (pin 9)
to Output Return (pin 8) may be trimmed 5ꢀ via a single trimpot or fi xed
resistor. The trimpot should be connected as shown in Figure 3 with its wiper
connected to pin 10 (Trim). A trimpot can also be used to determine the value
of a single fi xed resistor which can be connected between pin 10 (Trim) and
pin 9 (+5V Output) to trim "down" the output voltages, or between pins 10
(Trim) and 8 (Output Return) to trim "up" the output voltages. Fixed resistors
should have absolute TCR's less than 100ppm/°C to ensure stability.

Unlike most other DC/DC converters, BMP DC/DC's do not have their metal
case connected to one of their input pins. The "uncommitted" case is con-
nected to pin 4 which, depending on your system confi guration, should be
connected to either +Input (pin 3) or –Input (pin 2).
