Infineon Technologies introduces the TO-247 4pin package in conjunction with the latest CoolMOS™ technologies of 600V CoolMOS™ C7, 650V CoolMOS™ C7 and 600V CoolMOS™ P6. With new generations of power switches becoming faster and faster, the effect of the parasitic elements of package and board limit more and more the overall system performance. An effective measure to overcome this problem is to provide an additional connection to the source (Kelvin connection), that is used as a reference potential for the gate driving voltage, thereby eliminating the effect of voltage drops over the source inductance. The achievable efficiency improvement, resulting from faster switching transients, can in fact be significant.

 

Features  Benefits
  • 4 th pin (Kelvin source)
  • Increased creepage distance between high voltage pins
  • Gate signal optimization
  • Reduces parasitic source inductance effects on the gate circuit enabling faster switching and increased efficiency
  • Using benefits of Kelvin source efficiency to increase MOSFET R DS(on) and reduce BOM cost
  • Creepage distance meets 5000m altitude requirement
  • Easier to design by customer

Benefits in efficiency of 4pin versus 3pin variants

Performance gain of 0.6% full load efficiency can be achieved if the same die is used in a 4pin versus a 3pin package.

 

Lower full load losses with 4pin part allow for next ‘smaller’ MOSFET (60mΩ instead of 45mΩ), enabling a BOM cost reduction with better low load efficiency.

 

TO-247 4pin package offers higher efficiency by means of a dedicated source-sense pin

  • Parasitic source inductance counteracts drive voltage
  • Slow down of transient leads to lower efficiency
 
  • Separate pin “source-sense” (Kelvin source) delivering an undisturbed signal to the driver
  • Up to 3x lower switching losses lead to
    • Higher efficiency
    • Cost reduction potential in application

  • Isolated driver 1EDI60N12AF like for high side switch setup enables the floating of the kelvin source
  • No displacement current in the control circuit due to the isolation of the driver
  • Flexible driver supply: isolated and none isolated can be used
 
  • Kelvin source pin oscillates due to induced voltage spike on source inductance referring to power ground
  • MOSFET can be seen like high side switch in half bridge
  • Primary to secondary driver isolation eliminates impact to gate signal

Introducing the New CoolMOS™ C7 Series

Introducing the CoolMOS™ C7 series

Infineon’s new CoolMOS™ C7 series is a revolutionary step forward in technology, providing the worlds’s lowest RDS(on) per package and, thanks to its low switching losses, efficiency improvements over the full load range. C7 is optimized for hard switching topologies such as power factor correction (CCM PFC), two transistor forward (TTF) and solar boost in applications such as solar, server, telecom and UPS. The 650V breakdown voltage makes it suitable for both solar and switched mode power supplies (SMPS) PFC stages where extra safety margin is required.
