Introduction  
The PI31xx-xx-EVAL1 evaluation board allows the user to test the basic operating  
principles of the PI31xx series of high density DC-DC power converters and experience  
the performance and value of this solution compared to alternate conventional  
solutions. Each evaluation board is populated with the components that could be used  
in a final design. It is not designed or intended to be used in end product applications.  
Please read this document prior to the connection of test equipment and refer to the  
product datasheet for device specifications, descriptions and characteristics. Remember  
to follow good lab safety practices and use safety glasses at all times.

The PI31xx-xx-EVAL1 is configured to support one single input and one single output.  
Each board offers pin strap options for trimming the output voltage up and down,  
turning the converter on and off and adding EMI system “Y” capacitors. Additional  
parts are included to compensate for line impedance associated with long leads from  
the bench power supply to the converter. Additional component footprints are made  
available to allow the user to test different design configurations that may be required  
to meet their end needs. Kelvin type test points are included to allow for easy and  
convenient connections of testing instruments for evaluation of efficiency, line/load  
regulation and transient response. A low impedance oscilloscope connection using a  
Johnson jack is included for ripple measurement and evaluation of the output voltage  
during transient events. Each demo board is equipped with a heatsink to allow high  
power operation with a small amount of air flow and to allow operation of the board  
over various temperature extremes.
