PRODUCT OVERVIEW
Featuring a full 15 Watt output in one square
inch of board area, the BEI-15 series isolated DC/
DC converter family offers efficient regulated DC
power for printed circuit board mounting. The
wide range 4:1 inputs on the 0.96" x 1.1" x 0.35"
(24.4 x 27.9 x 8.9 mm) 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 BEI-15 series includes full magnetic
and optical isolation with Basic protection up to
2250 Volts DC (Q48 models) and 2000 VDC (Q12
models). 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.
