Description

Ordering Information

Pin-Out Information

The PT3320 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 30 watts or 8 A. Standard output

voltages range from 1.8 V to 15 V, each

adjustable by up to 10% of nominal.

Operating features include a remote

on/off control, an under-voltage-lockout

(UVLO), and a differential remote sense.

The PT3320 series also incorporates

many protection features. These include

output current limit, short-circuit pro-

tection, and over-temperature shutdown.

A 330µF of output capacitance is

required for proper operation.

PT 3321r = 3.3V/8A (26.4W)

PT 3322r = 5.0V/6A

PT 3323r = 12.0V/2.5A
