PRODUCT OVERVIEW
The new 1.2, 1.5V, 1.8V and 2.5V models in
Murata Power Solutionsâ ï¬agship 7-15 Watt
A-Series can source a continuous 6 Amps. This
is the most "low-voltage" current available from
a standard 1" x 2" package, and these power
converters exemplify Murata Power Solutionsâ
relentless drive to bring you more power/current,
from standard packages, without compromising
reliability or resorting to thermal specmanship.
By combining a high-frequency, high-efï¬ciency
(to 88%), synchronous-rectiï¬er topology with
the newest components and time-tested, fully
automated, SMT-on-pcb construction, these
UWR Models are able to bring you 7-15W (@
up to 6A) in the standard 1" x 2" package from
which most competitors can only get 5-10W (@
3-4A). All UWRâs deliver their full output power
over ambient temperature ranges from â40°C
to as high as +70°C (model and input voltage
dependent) without heat sinks or supplemental
forced-air cooling. Devices derate to +100°C.
Output voltages are 1.2, 1.5, 1.8, 2.5, 3.3, 5,
12 or 15 Volts. Input voltage ranges are 10-18V
(D12 models), 18-36V (D24 models) or 36-75V
(D48 models). All models feature input pi ï¬lters,
input undervoltage and overvoltage lockout, input
reverse-polarity protection, output overvoltage
protection, output current limiting, and continuous
short-circuit protection. On/off control and output-
trim functions are optional (see Optional Functions).
All models are designed to meet IEC950, UL1950
and EN60950-1, 2nd Edition safety requirements.
D48 models (36-75V inputs) are CE marked.
UWR 7-15W DC/DCâs are packaged in low-
cost, light-weight, diallyl phthalate (UL94V-0
rated) plastic packages with standoffs. EMC
compliance is achieved via a low-noise design
rather than through expensive metal shielding.
