Description

Ordering Information

Pin-Out Information

The PT4560 series is a single-output

isolated DC/DC converter, housed in a

19-pin space-saving package. These mod-

ules are UL, CSA, and VDE approved

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 10ꢀ of nominal.

Operating features include a remote

on/off control, an under-voltage-lockout

(UVLO), and a differential remote sense.

The PT4560 series also incorporates

many protection features. These include

output current limit, short-circuit pro-

tection, and over-temperature shutdown.

PT4560 requires a 330µF of output

capacitance for proper operation.
