UEP11-18

The UEP 11-18Watt series DC/DC converter is an alternative pinout for DATEL's fl agship A-Series. An external pinout confi guration affords the design layout to be oriented for optimal thermal performance thereby increasing available output power as much as 20%. Available in a 1" x 2" package, these converters can deliver up to 18 Watts at the same ambient temperatures as their 15 Watt counterparts.

By combining a high-frequency (340kHz), high-effi ciency (to 88%), synchronousrectifi er topology with the newest components and time-tested, fully automated, SMT-on-pcb construction, these UEP Models are able to bring you 11-18W in the standard 2" x 1" package from which most competitors can only get 5-10W. All UEP'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 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 fi lters, input undervoltage and overvoltage lockout, input reverse-polarity protection, output overvoltage protection, output current limiting, and continuous short-circuit protection. Standard features also include On/Off Control and outputtrim. All models are certifi ed to IEC950, UL60950 and EN60950 safety requirements for OPERATIONAL insulation. "D48" models (36-75V inputs) are CE marked.

UEP 11-18W 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.
