30 WATT ISOLATED

DC/DC CONVERTER

The PT3320 is a new series of high-

input voltage, 30 Watt, isolated DC to

DC converters housed in a unique

vertical or horizontal 19-pin SIP pack-

age. The 36 to 75V input range allows

easy integration into many distributed

power applications which utilize 48V bus

architectures.

110% of nominal with the addition of an

external resistor. Other easy to use

features include an inhibit function and

differential remote sense which auto-

matically compensates for any voltage

drop from the converter to the load. The

PT3320 includes built in current limit,

short circuit protection and over-

temperature shutdown.

The PT3320 series is available with

output voltages from 2V to 15V. The

output voltage is adjustable from 90 to

The PT3320 requires a 330µF output

capacitor for proper operation.
