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
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.
