FEATURES
PRODUCT OVERVIEW

Five-sided shielded metal package reduces
radiated emissions
Featuring a full 15 Watt output in one square
inch of board area, the BPM15 series isolated
DC-DC converter family offers efficient regulated
DC power for printed circuit board mounting. The
wide range 4:1 inputs on the 1" x 1" x 0.40" (25.4
x 25.4 x 10.16mm) converter are either 9 to 36
Volts DC (Q12 models) or 18 to 75 Volts DC (Q48
models), ideal for battery-powered and telecom
equipment. The industry-standard pinout fits larger
1" x 2" converters. Fixed output voltages of ±5,
±12 or ±15 VDC are regulated to within ±0.25%.
Applications include small instruments, arealimited microcontrollers, data communications
equipment, remote sensor systems, vehicle and
portable electronics.
The rugged mechanical, thermal, and electrical
design of this product is intended for high reliability
and harsh environments.

Industry standard 1" x 1" x 0.40"
encapsulated package and pinout

Wide range input voltages 9-36 and
18-75 Vdc

Bipolar ±5V, ±12V and ±15V outputs

Up to 15 Watts or greater total output
power with overtemperature shutdown

Isolation up to 1600 VDC (basic)

High efficiency flyback topology

Usable -40 to 85°C temperature range
(with derating)

Assembly and attachment for RoHS standards

Extensive self-protection shut down
features
The BPM15 series includes full magnetic and
optical isolation with Basic protection up to 1600
Volts DC. For powering digital systems, the outputs
offer fast settling to step transients and will accept
higher capacitive loads. Excellent ripple and noise
specifications assure compatibility to noise-susceptible circuits. For systems requiring controlled
startup/shutdown, an external remote On/Off
control may use a switch, transistor or digital logic.
A wealth of self-protection features avoid both
converter and external circuit faults. These include
input undervoltage lockout and overtemperature
shutdown. The outputs current limit using the
“hiccup” autorestart technique and the outputs
are short-circuit protected. Additional features
include output overvoltage and reverse conduction
elimination. The high efficiency offers minimal heat
buildup and “no fan” operation.

TECHNICAL NOTES
Input Fusing
Certain applications and/or safety agencies may require fuses at the inputs of
power conversion components. Fuses should also be used when there is the
possibility of sustained input voltage reversal which is not current-limited. For
greatest safety, we recommend a fast blow fuse installed in the ungrounded
input supply line.
The installer must observe all relevant safety standards and regulations. For
safety agency approvals, install the converter in compliance with the end-user
safety standard.
Input Under-Voltage Shutdown and Start-Up Threshold
Under normal start-up conditions, converters will not begin to regulate properly
until the rising input voltage exceeds and remains at the Start-Up Threshold
Voltage (see Specifications). Once operating, converters will not turn off until
the input voltage drops below the Under-Voltage Shutdown Limit. Subsequent
restart will not occur until the input voltage rises again above the Start-Up
Threshold. This built-in hysteresis prevents any unstable on/off operation at a
single input voltage.
Users should be aware however of input sources near the Under-Voltage
Shutdown whose voltage decays as input current is consumed (such as poorly
regulated capacitor inputs), the converter shuts off and then restarts as the
external capacitor recharges. Such situations could oscillate. To prevent this,
make sure the operating input voltage is well above the UV Shutdown voltage
AT ALL TIMES.
Start-Up Delay
Assuming that the output current is set at the rated maximum, the Vin to Vout
Start-Up Delay (see Specifications) is the time interval between the point when
the rising input voltage crosses the Start-Up Threshold and the fully loaded
regulated output voltage enters and remains within its specified regulation
band. Actual measured times will vary with input source impedance, external
input capacitance, input voltage slew rate and final value of the input voltage
as it appears at the converter.
These converters include a soft start circuit to moderate the duty cycle of the
PWM controller at power up, thereby limiting the input inrush current.
The On/Off Remote Control interval from inception to Vout regulated
assumes that the converter already has its input voltage stabilized above the
Start-Up Threshold before the On command. The interval is measured from the
On command until the output enters and remains within its specified accuracy
band. The specification assumes that the output is fully loaded at maximum
rated current.
Recommended Input Filtering
The user must assure that the input source has low AC impedance to provide
dynamic stability and that the input supply has little or no inductive content,
including long distributed wiring to a remote power supply. The converter will
operate with no additional external capacitance if these conditions are met.
For best performance, we recommend installing a low-ESR electrolytic
capacitor immediately adjacent to the converter’s input terminals. Initial suggested capacitor values are 10 to 22 μF, rated at twice the expected maxi-
mum input voltage. Make sure that the input terminals do not go below the
undervoltage shutdown voltage at all times. More input bulk capacitance may
be added in parallel (either electrolytic or tantalum) if needed.
Recommended Output Filtering
The converter will achieve its rated output ripple and noise with no additional
external capacitor. However, the user may install more external output capacitance to reduce the ripple even further or for improved dynamic response.
Again, use low-ESR ceramic (Murata GRM32 series) or polymer capacitors.
Initial values of 10 to 47 μF may be tried, either single or multiple capacitors in
parallel. Mount these close to the converter. Measure the output ripple under
your load conditions.
Use only as much capacitance as required to achieve your ripple and noise
objectives. Excessive capacitance can make step load recovery sluggish or
possibly introduce instability. Do not exceed the maximum rated output capacitance listed in the specifications.
Input Ripple Current and Output Noise
All models in this converter series are tested and specified for input reflected
ripple current and output noise using designated external input/output components, circuits and layout as shown in the figures below. The Cbus and Lbus
components simulate a typical DC voltage bus. Please note that the values of
Cin, Lbus and Cbus may vary according to the specific converter model.

Encapsulated Isolated Wide Input Bipolar 15-Watt DC-DC Converters
Minimum Output Loading Requirements
All models regulate within specification and are stable under 10% minimum
load to full load conditions. Operation under no load might however slightly
increase output ripple and noise.
Thermal Shutdown
To protect against thermal overstress, these converters include thermal
shutdown circuitry. If environmental conditions cause the temperature of the
DC-DC’s to rise above the Operating Temperature Range up to the shutdown
temperature, an on-board electronic temperature sensor will power down
the unit. When the temperature decreases below the turn-on threshold, the
converter will automatically restart. There is a small amount of temperature
hysteresis to prevent rapid on/off cycling.
CAUTION: If you operate too close to the thermal limits, the converter may
shut down suddenly without warning. Be sure to thoroughly test your application to avoid unplanned thermal shutdown.
Temperature Derating Curves
The graphs in this data sheet illustrate typical operation under a variety of
conditions. The Derating curves show the maximum continuous ambient air
temperature and decreasing maximum output current which is acceptable
under increasing forced airflow measured in Linear Feet per Minute (“LFM”).
Note that these are AVERAGE measurements. The converter will accept brief
increases in current or reduced airflow as long as the average is not exceeded.
Note that the temperatures are of the ambient airflow, not the converter
itself which is obviously running at higher temperature than the outside air.
Also note that very low flow rates (below about 65 LFM) are similar to “natural
convection”, that is, not using fan-forced airflow.
Murata Power Solutions makes Characterization measurements in a closed
cycle wind tunnel with calibrated airflow. We use both thermocouples and an
infrared camera system to observe thermal performance.
CAUTION: If you exceed these Derating guidelines, the converter may have
an unplanned Over Temperature shut down. Also, these graphs are all collected
near Sea Level altitude. Be sure to reduce the derating for higher altitude.
Output Current Limiting
Current limiting inception is defined as the point at which full power falls
below the rated tolerance. See the Performance/Functional Specifications.
Note particularly that the output current may briefly rise above its rated value
in normal operation as long as the average output power is not exceeded. This
enhances reliability and continued operation of your application. If the output
current is too high, the converter will enter the short circuit condition.
Output Short Circuit Condition
When a converter is in current-limit mode, the output voltage will drop as the
output current demand increases. If the output voltage drops too low (approximately 98% of nominal output voltage for most models), the PWM controller
will shut down. Following a time-out period, the PWM will restart, causing
the output voltage to begin rising to its appropriate value. If the short-circuit
condition persists, another shutdown cycle will initiate. This rapid on/off cycling
is called “hiccup mode”. The hiccup cycling reduces the average output current, thereby preventing excessive internal temperatures and/or component
damage.
Remote On/Off Control
The remote On/Off Control can be specified with either logic logic type. Please
refer to the Connection Diagram on page 1 for On/Off connections.
Positive-logic models are enabled when the On/Off pin is left open or is
pulled high to +Vin with respect to –Vin. Therefore, the On/Off control can be
disconnected if the converter should always be on. Positive-logic devices are
disabled when the On/Off is grounded or brought to within a low voltage (see
Specifications) with respect to –Vin.
Negative-logic devices are on (enabled) when the On/Off pin is grounded or
brought to within a low voltage (see Specifications) with respect to –Vin. The
device is off (disabled) when the On/Off is pulled high (see Specifications) with
respect to –Vin.
Dynamic control of the On/Off function must sink the specified signal current
when brought low and withstand the specified voltage when brought high.
Be aware too that there is a finite time in milliseconds (see Specifications)
between the time of On/Off Control activation and stable, regulated output. This
time will vary slightly with output load type and current and input conditions.
Output Capacitive Load
These converters do not require external capacitance added to achieve rated
specifications. Users should only consider adding capacitance to reduce
switching noise and/or to handle spike current load steps. Install only enough
capacitance to achieve your noise and surge response objectives. Excess
external capacitance may cause regulation problems and possible oscillation
or instability.
The maximum rated output capacitance and ESR specification is given for a
capacitor installed immediately adjacent to the converter.
Floating Outputs
Since these are isolated DC-DC converters, their outputs are "floating." Any
BPM15 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, with either output grounded. The Common
pin should be left open. Minimum 10% loading is recommended under these
conditions.
