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.
