Thermal Considerations  
The PI31xx-xx-EVAL1 is supplied with optional heat sinks. At present, Picor offers four  
different heat sink options to accommodate the customers space and cooling needs.  
Heatsinks are available in two sizes, one with 6.3mm fins and the other with 11mm fins.  
Each of those heatsinks can be ordered with a specific air flow direction in mind, both  
cross flow and longitudinal are supported. Please refer to the product website  
www.vicorpower.com for more information.
