PRODUCT OVERVIEW
Murata Power Solutions’ MAPC-104 non-isolated,
triple output DC/DC converter is designed to
power the Cisco 3200 Mobile Access Router and
is compliant to PC/104-Plus specifications. The
equipment ideally suites integration into public
safety, defense, homeland security and commercial
transportation vehicles, whether on land, in water
or air, and is employed for powering secure data,
voice and video communications across multiple
wireless networks.
The MAPC-104 is a high performance, compact
and rugged power supply which operates in the
harshest conditions, withstanding input transient
voltages according to SAE J1455 and J1211. It
converts the vehicle’s standard battery voltage of
12V or 24V (VIN range from 9 to 32 Volts) to three
fully regulated outputs of 3.3V @ 6A, 5.1V @ 6.3A
and 12V @ 100mA up to a total output power of
46 Watts. Taking full advantage of a synchronous-
rectifier, buck/boost topology, MAPC-104’s boast
outstanding efficiency of up to 92.5%, enabling
full-power operation to ambient temperatures as
high as +85°C with 100 lfm air flow.
The compact 3.775” x 3.55” x 0.60” (95.9 x
90.2 x 15.2mm) open frame, triple output DC/DC
power card is mechanically and electrically compli-
ant to PC/104-plus specifications. Operating with
the Cisco designed system cards, the MAPC-104
is considered part of the host, which requires the
3.3V (but no –5V/–12V) supply provided.
Assembled using fully automated, SMT-on-pcb
techniques, MAPC-104s provide stable no-load
operation, excellent line and load regulation
(±1% max.), quick step response (200μsec), and
low output ripple/noise (25mVp-p).
All devices feature full I/O fault protection
including: input overvoltage and undervoltage
shutdown, power up/down sequencing, output
overvoltage, output current limiting, short-circuit
protection, power good (LED indicator and external
signal), overtemperature warning and thermal
shutdown.
All models are certified to IEC/EN/UL60950-1
safety standards. Selected models include RoHS
compliance.

~ Typical at TA = +25°C under nominal line voltage and nominal-load conditions, unless noted.
 Ripple/Noise (R/N) is tested/specified over a 20MHz bandwidth. All models are specified
with an external 0.1μF multi-layer ceramic capacitor installed across each output pin.
€ Devices have no minimum-load requirements and will regulate under no-load conditions.
Regulation specifications describe the output-voltage deviation as the line voltage or load
is varied from its midpoint value to either extreme.
