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.
