    Description

    The LMG341xR050 GaN power stage with integrated driver and protection enables designers to achieve new levels of power density and efficiency in power electronics systems. The LMG341x’s inherent advantages over silicon MOSFETs include ultra-low input and output capacitance, zero reverse recovery to reduce switching losses by as much as 80%, and low switch node ringing to reduce EMI. These advantages enable dense and efficient topologies like the totem-pole PFC.

    The LMG341xR050 provides a smart alternative to traditional cascode GaN and standalone GaN FETs by integrating a unique set of features to simplify design, maximize reliability and optimize the performance of any power supply. Integrated gate drive enables 100 V/ns switching with near zero Vds ringing, less than 100 ns current limiting response self-protects against unintended shoot-through events, overtemperature shutdown prevents thermal runaway, and system interface signals provide self-monitoring capability.
