Cool-Power® Rev 1.4 vicorpower.com Page 16 of 18 02/2015 800 927.9474 PI31xx-01-HVIZ TM The TM pin serves as an output indicator of the internal package temperature which is within +/- 5°K of the hottest junction temperature. Because of this, it is a good indicator of a thermal overload condition. The output is a scaled, buffered analog voltage which indicates the internal temperature in degrees Kelvin. Upon a thermal overload, the TM pin is pulled low, indicating a thermal fault has occurred. Upon restart of the converter, the TM pin reverts back to a buffered monitor. The thermal shutdown function of the PI31xx- 01-HVIZ is a fault feature which interrupts power processing if a certain maximum temperature is exceeded. TM can be monitored by an external microcontroller or circuit configured as an adaptive fan speed controller so that air flow in the system can be conveniently regulated. SGND The PI31xx-01-HVIZ SGND pin is the “quiet” control circuitry return. It is basically an extension of the internal signal ground. To avoid contamination and potential ground loops, this ground should NOT be connected to -IN since it is already star connected inside the package. Connect signal logic to SGND. Output Power Pins +OUT And -OUT The output power terminals OUT(+) and OUT(-) deliver the maximum output current from the PI31xx-01-HVIZ through the J-lead output pins. This configuration allows for a low impedance output and should be connected to multi-layer PCB parallel planes for best performance. Due to the high switching frequency, output ripple and noise can be easily attenuated by adding just a few high quality X7R ceramic capacitors while retaining adequate transient response for most applications. The PI31xx-01-HVIZ does not require any feedback loop compensation nor does it require any opto- isolation. All isolation is contained within the package. This greatly simplifies the use of the converter and eliminates all outside influences of noise on the quality of the output voltage regulation and feedback loop. It is important for the user to minimize resistive connections from the load to the converter output and to keep stray inductance to a minimum for best regulation and transient response. The very small size footprint and height of the PI31xx-01-HVIZ allows the converter to be placed in the optimum location to allow for tight connections to the point of load. For those applications absolutely requiring very tight regulation, contact Picor Engineering at vicorpower.com for a remote sense application circuit which can be used.
