DATEL's fully isolated UHP series of DC/DC converters affords users a practical
solution for their low-voltage/high-current applications . With an input voltage range of
36 to 75 Volts, the UHP-3.3/30-D48 delivers 30 Amps of output current from a fully
regulated 3.3V output. Using both surface-mount technology and planar magnetics,
these converters are manufactured on a 2.3" x 2.4" open-frame package with an
industry-standard pinout confi guration.
UHP converters utilize a full-bridge, fi xed-frequency topology along with syn-
chronous output rectifi cation to achieve a high effi ciency of 89%. This effi ciency,
coupled with the open-frame package that allows unrestricted air fl ow , reduces
internal component temperatures thereby allowing operation at elevated ambient
temperatures.
These DC/DC's provide output trim, sense pins and primary side on/off control
(available with positive or negative logic) or sync. Standard features also include
input overvoltage and undervoltage shutdown circuitry, output overvoltage protection, output short-circuit and current limiting protection and thermal shutdown. All
devices meet IEC950, UL1950 and EN60950 safety standards and carry the CE
mark (meet LVD) requirements). CB reports are available on request.

UHP 30 Amp DC/DC's are designed so a negative logic
on/off control ("N" suffi x) or a Sync function ("S" suffi x) can be
added in the pin 3 position.
