Infineon’s high speed devices are used to reduce the size of the active components (25kHz --> 70kHz). Infineon’s HighSpeed 3 family provides the best compromise between switching and conduction losses. The key feature of this family is a MOSFET-like turn-off switching behavior, leading to low turn off losses. Furthermore, up to 15% efficiency improvement can be achieved by implementing this technology in your design.
Summary of Features:
Designed specifically to replace planar MOSFETs in applications switching at frequencies below 70kHz
Low switching losses for high efficiency
Excellent V ce(sat) behavior thanks to the famous Infineon TRENCHSTOP™ technology
Fast switching behavior with low EMI emissions
