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.
