New 15 V silicon trench MOSFET technology optimized for high frequency switching buck converters at low input voltages

Inhalt:
Driven by emerging technologies such as AI, blockchain, 5G and virtual reality global servers, power consumption has increased by >250 % since 2017. In this context, a 48 V power distribution architecture has been proposed by leading tech companies. This also anticipates stricter environmental regulations and enables further capacity upscaling. Infineon's newly introduced 15 V trench power MOSFET plays a key role in converting the 48 V to a CPU/GPU supply voltage level thanks to significantly improved device characteristics. This paper presents benchmark results for the discrete MOSFET generations as well as for a fully integrated power stage operating up to 2 MHz.
