Description  
Ordering Information  
Pin-Out Information  
The PT4410 series of power modules are single-  
output isolated DC/DC converters, housed in a  
compact 21-pin low-profile (12 mm) package.  
These modules are rated up to 100W with load  
currents as high as 30 A. The output voltage is set  
within a pre-defined range via a 5-bit input code.  
The PT4410 series operates from a standard  
48-V telecom CO supply and occupies only 3.9 in²  
of PCB area. These modules offer OEMs a compact  
and flexible high-output power source for use with  
high-end microprocessors, DSPs, general purpose  
logic and analog. They are suitable for distributed  
power applications in both telecom and computing  
environments.  
Features include output over-current protection,  
on/off control, output over-voltage protection  
(OVP), over-temperature shutdown, under-volt-  
age lockout (UVLO), and an output differential  
remote sense. The modules are fully integrated  
for stand-alone operation, and require no additional  
components. The horizontal package outline is also  
comparable to industry standard ¼-bricks, allowing  
for a dual PWB layout.
