UWR Models  
s
Single Output, High-Density,  
6 Amp/15 Watt DC/DC Converters  
Typical units  
PRODUCT OVERVIEW  
The new 1.2, 1.5V, 1.8V and 2.5V models in  
Murata Power Solutions’ flagship 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 Solutions’  
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-effi-  
ciency (to 88%), synchronous-rectifier 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 UWR’s deliver their full output power  
over ambient temperature ranges from –40°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, 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 filters,  
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 Func-  
tions). All models are designed to meet IEC950,  
UL1950 and EN60950-1 safety requirements.  
D48 models (36-75V inputs) are CE marked.  
UWR 7-15W DC/DC’s 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.  
FEATURES  
1.2-2.5VOUT models source 6 Amps  
3.3VOUT models source 4.25 Amps  
5/12/15VOUT models deliver full 15 Watts  
Synchronous-rectifier topologies  
Guaranteed efficiencies to 88%  
Choice of 3 input voltage ranges:  
10-18V, 18-36V, 36-75V  
–40 to +60/70°C ambient w/o derating  
Fully isolated (1500Vdc); I/O protected  
Designed to meet UL1950/EN60950-1
