Description

Ordering Information

Pin-Out Information

The PT3340 series is a single-output

isolated DC/DC converter, housed in a

19-pin aluminum SIP package. These

modules are UL, CSA, and VDE ap-

proved for telecom applications, and

rated at 30W or 8A. The 18V to 60V

input range allows easy integration into

many distributed power applications which

utilize 24V bus architectures.

Standard output voltages range from

1.8V to 15V, and are each adjustable by

up to 10ꢀ. Operating features include

a Remote On/Off control, an under-voltage

lockout (UVLO), and a differential re-

mote sense. Protection features include

an output current limit, short-circuit

protection, and over-temperature shut-

down.

PT 3341r = 3.3V/8A (26.4W)

PT 3342r = 5.0V/6A

PT 3343r = 12.0V/2.5A

PT 3344r = 15.0V/2A
