Features
High-Density, " x 2"
6 Amp/5 Watt, .2-5VOUT DC/DC's
Figure 1. Simplified Schematic
The new .2, .5V, .8V and 2.5V models in C&D’s flagship 7-5 Watt A-Series
can source a continuous 6 Amps. This is the most "low-voltage" current available
from a standard " x 2" package, and these power converters exemplify C&D’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 7-5W (@ up to 6A) in the
standard " x 2" package from which most competitors can only get 5-0W (@ 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 +00°C.
Output voltages are ,2, .5, .8, 2, 2.5, 3.3, 5, 2 or 5 Volts. Input voltage
ranges are 0-8V (D2 models), 8-36V (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, UL950 and
EN60950 safety requirements. D48 models (36-75V inputs) are CE marked.
UWR 7-5W 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.
