Pin-Out Information  
Pin Function  
(5.4W)  
The PT4220 power modules are a  
series of DC/DC converters housed in  
an ultra-low profile (8mm) solderable  
copper case. The series includes a num-  
ber of preset output voltages ranging  
from 1.3V up to 12V, all fully approved  
forTelecomuse. T heymayalsobeused  
in many other applications that require  
input-output isolation over an extended  
temperature range. The modules are an  
ideal choice for low-power digital and  
analog circuits, including DSPs and  
microcontrollers. The flexibility of  
input-output isolation also allows the  
output to be configured for negative  
voltage operation.
