TWR A-Series

www.murata-ps.com

12-15W, Triple Output DC-DC Converters

Featuring Murata Power Solutions' ultra-wide, 18-72V, input voltage

range, this Family of A-Series, TWR (triple-output) DC-DC converters

deliver up to 15 Watts.

PRODUCT OVERVIEW

Typical units

These devices each have a primary +5V output

that can source from 1 Amp to 1.5 Amps (model

dependent) and auxiliary 12ꢀ15V outputs that can

source from 15ꢁ to 25ꢁmA (model dependent).

All models can simultaneously source maximum

rated current from both primary and auxiliary

outputs. The nominal input voltage for each model

is 48V.

qualiﬁcation program that includes HALT (Highly-

Accelerated Life Testing), which is designed to

detect any potential electrical, mechanical or proc-

ess weakness.

Packaged in standard, 2" x 2" x ꢁ.45", shielded

metal cases with non-conductive coatings, these

fully isolated (1ꢁꢁꢁVdc minimum) DC-DC’s offer

excellent line and load regulation. Additionally,

these A-Series triples have non-latching output

current limiting, input overvoltage shutdown, input

reverse-polarity protection, and output overvoltage

clamping to protect both the power converters and

their loads. All A-Series TWR models are fully EMI

characterized and designed to meet UL195ꢁ, IEC

95ꢁ, CSA 95ꢁ and EN6ꢁ95ꢁ.

FEATURES

As members of Murata Power Solutions’ new

A-Series, the 12-15W triples exhibit both low cost

and outstanding long-term reliability. Their design

combines straightforward circuit topologies, proven

SMT-on-pcb construction methods, the newest

components, and highly repeatable automatic-

assembly techniques. The A-Series TWR’s superior

durability is substantiated by a rigorous in-house
