Wide Input Voltage Range: 38V to 72V high switching frequencies, thick-film technol-  
83% Efficiency  
ogy and a high degree of silicon integration.  
The high reliability and very low package  
height makes these converters ideal for  
Telecom and Datacom applications requiring  
input-to-output isolation with board spacing  
down to 0.6”.  
The PT4200 series is offered in a unique  
molded through-hole or SMD-DIP package  
with single output voltages of 2V, 3.3V, 5V,  
and 12V, dual outputs of 5V, +5V/+3.3V, and  
12V.  
1,500 VDC Isolation  
18 Pin DIP Package  
3.5 Million Hour MTBF  
Meets FCC/EN55022 Class A  
UL and CSA approved  
No External Components Required  
Adjustable Output Voltage  
The PT4200 series of isolated DC/DC  
converters advance the state-of-the-art for  
board-mounted converters by employing
