The new 1.2, 1.5V, 1.8V and 2.5V models in DATEL’s 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 DATEL’s

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-efficiency (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 Functions). All models are certified to IEC950, UL1950 and

EN60950 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.
