4 / 14 page UG:301 vicorpower.com Applications Engineering: 800 927.9474 Page 4 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. Pin Type Description Name IN+ Input/Lug Primary side positive input voltage terminal. IN- Input/Lug Primary side negative input voltage terminal. OUT+ Output/Lug Isolated secondary DC output voltage positive terminal. OUT- Output/Lug Isolated secondary DC output voltage negative terminal. TM Test/Pin Temperature measurement output pin with respect to SGND. 3V=300°K 10mV/°K SGND Test/Pin Signal ground, primary side referenced. TRIM/SS Test/Pin Monitor pin for the soft start voltage and trim voltage reference with respect to SGND. ENABLE Test/Pin Allows for monitoring of the ENABLE signal with respect to SGND. INN Test/Pin Kelvin sense connection for input supply (-) and input voltage measurement test point. INP Test/Pin Kelvin sense connection for input supply (+) and input voltage measurement test point. YN Output/Pad Optional test pad for connection of optional “YN” capacitor to external system ground. YP Output/Pad Optional test pad for connection of optional “YP” capacitor to external system ground. OUTP Test/Pin Kelvin sense connection for output voltage (+) and output voltage measurement test point. OUTN Test/Pin Kelvin sense connection for output voltage (-) and output voltage measurement test point. OUT Test/PIn PCB test jack for low noise measurement of the output voltage.
