Description
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 鹵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 330碌F of output capacitance is
required for proper operation.
