Features
DC/DC Converters now comes to you in the standard "half-brick" configuration (2.3"
x 2.4" x 0.52"). All models in our new UCP Series meet UL/EN60950 safety require-
N _{Standard "half-brick" configuration}
ments, including each European country’s deviations. A CB Test Certificate/Report
N _{UL/EN60950 safety approvals}
is available. All models have BASIC insulation; guarantee 1500Vdc isolation; and
(BASIC insulation)
because they are designed with Class B thermal insulation, satisfy all safety require-

ments over their full operating temperatures.
UCP Models are designed for demanding telecom, datacom and networking
applications. Their "semi-synchronous-rectifier" design (400kHz switching) achieves
impressive efficiencies (up to 88%). Output voltages are 12 or 15 Volts. Input
voltage ranges are 10-18V ("D12" models), 18-36V ("D24" models) or 36-75V
N VIN ranges: 10-18V, 18-36V, 36-75V
("D48" models). "D48" models meet the Low Voltage Directive (LVD) and carry the

For high reliability and affordability, DATEL utilizes high-speed automatic assem-
bly to construct the UCP’s proven SMT-on-pcb designs. All models have been rigor-
ously qualified (including a 500-hour life test) and EMC characterized. Devices are

housed in metal cases (with non-conductive baseplates) that incorporate threaded

inserts for add-on heat sinks and/or pcb mounting.
N On/off, VOUT trim and sense functions
N Modifications and customs for OEM’s
UCP’s feature input pi filters, input undervoltage and overvoltage lockout, output
current limiting, short-circuit protection, and thermal shutdown. Additionally, all
devices have output trim capability and an on/off control pin that can be ordered
with either polarity. We can easily modify standard-product UCP’s to meet your
application-specific requirements.

 12V- and 15V-output models have a standard forward architecture in which this FET is replaced
with a Schottky diode.
