Description
The PT4580 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
30W or 8A. The 18V to 60V input range
allows easy integration into many distrib-
uted power applications which utilize 24V
bus architectures.
Standard output voltages range from
1.8V to 15V, and are each adjustable by
up to 鹵10%. 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.
A 330碌F output capacitor is required
for proper operation.
