3.3 Volts @ 30 Amps
100 Watt, DC/DC Converters
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 configuration.

Regulated 3.3V output @ 30 Amps
ꢀ
Input range: 36V-75V
ꢀ
Open frame: 2.3" x 2.4" x 0.47"
ꢀ
Industry-standard package/pinout
UHP converters utilize a full-bridge, fixed-frequency topology along with syn-
chronous output rectification to achieve a high efficiency of 89%. This efficiency,
coupled with the open-frame package that allows unrestricted air flow, reduces
internal component temperatures thereby allowing operation at elevated ambient
temperatures.

Fully isolated, 1500Vdc guaranteed
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 protec-
tion, 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.

CASE
UHP converters have a trim capability (pin 7) that allows users to adjust the
output voltage 5%. Adjustments can be accomplished via a trim pot, Figure 2,
or a single fixed resistor as shown in Figures 3 and 4. A single fixed resistor
can increase or decrease the output voltage depending on its connection.
Fixed resistors should have absolute TCR's less than 100ppm/°C to minimize
sensitivity to changes in temperature.

A single resistor connected from the Trim (pin 7) to the +Sense (pin 6), see
Figure 3, will increase the output voltage. A resistor connected from the Trim
(pin 7) to the –Sense (pin 8) will decrease the output voltage. See Figure 4.
