Features
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.
The PT3320 series is available with
output voltages from 2V to 15V. The
output voltage is adjustable from 90 to
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 requires a 330F output
capacitor for proper operation.
