Single Output, High Reliability, 2" x 1", 6-10 Watt, DC-DC Converters
FEATURES
Low Cost! Highly reliable!
Proven SMT-on-pcb construction
PRODUCT OVERVIEW
Designed to meet UL/EN/IEC 60950-1,
CAN/CSA-C22.2 60950-1
Qual tested; HALT tested; EMC tested
Placing reliability and cost considerations above
all others, Murata Power Solutions' new A-Series DC/
DC Converters combine straightforward circuit topologies, the newest components, proven SMT-on-pcb
construction, and highly repeatable automatic assembly techniques. Considering the critical low-cost and
long-term-reliability requirements of today’s telecom,
datacom and computer/networking applications, the
A-Series may well be the most cost-effective DC/DC’s
available today.
The single-output, 6-10 Watt Models of the
A-Series deliver both high power densities and
impressive MTBF’s. Their superior durability is
substantiated by a rigorous in-house qualification program including HALT (Highly Accelerated Life Testing).
The goal of HALT is not to simulate field conditions but
to expose devices to multiple excessive stresses with
Small packages, 2" x 1" x 0.375"
Standard pinouts
5, 5.2, 12 or 15 Volt outputs
Choice of 3 wide-range inputs:
4.7-7.25 Volts
9-18 Volts
18-75 Volts
Fully isolated, 1500Vdc guaranteed
–40 to +100°C operation
5-side metal shielded cases with nonconductive baseplates
Modifications and customs for OEMs
the intention of precipitating any potential electrical,
mechanical or process weaknesses.
Packaged in 2" x 1" x 0.375" shielded metal
cases with non-conductive coatings, these fully
isolated (1500Vdc guaranteed) DC/DC’s offer excellent
line/load regulation, full I/O protection, and industrystandard pinouts.
Output voltages include 5, 5.2, 12 and 15 Volts.
Input voltage ranges are either 4.7-7.25V ("D5A"
models), 9-18V ("D12A" models) or 18-75V ("D48A"
models). All A-Series UWR models are fully EMI characterized and agency safety approved.
A-Series DC/DC’s are extremely reliable, easyto-use, cost-effective power converters. Use them
to improve the reliability of existing equipment or to
develop new systems that exceed design objectives.
