PRODUCT OVERVIEW
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, area-
limited 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.
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-sus-
ceptible 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.

➀
Please refer to the part number structure for additional options and complete
ordering part numbers.
➁
The minimum output load for the BPM15 series is 10% of maximum current to
meet published specifications. The converter will not be damaged by less than
10% load but some specs may degrade slightly.
➂
All specifications are at nominal line voltage and full load, +25 °C. unless other-
wise noted. See detailed specifications and notes for full conditions.
Output capacitors are 1 μF ceramic in parallel with 10 μF. The input cap is 100 μF,
low ESR electrolytic.
I/O caps are necessary for our test equipment and may not be needed for your
application.
➃
RoHS-6 compliance does not claim EU RoHS exemption 7b (lead in solder).
➄
Balanced loads, 10% to 100% loads.

Notes
➀
Unless otherwise noted, all specifications are at nominal input voltage, nominal output voltage and
full load. General conditions are +25˚ Celsius ambient temperature, near sea level altitude, natural
convection airflow. All models are tested and specified with external parallel 1 μF and 10 μF output
capacitors. The external input capacitor is 100 μF, electrolytic.
➁
Input (back) ripple current is tested and specified over 5 Hz to 20 MHz bandwidth. Input filtering is
Cbus = 220 μF, Cin = 33 μF and Lbus = 12 μH.
➂
The Remote On/Off Control is referred to -Vin.
