9.1 Application Information
The LMG3410 is a single-channel GaN power stage targeting high-voltage applications. It targets hard-switched
and soft-switched applications running from a 350 V to 480 V bus such as power-factor correction (PFC)
applications. As GaN devices such as the LMG3410 have zero reverse-recovery charge, they are well-suited for
hard-switched half-bridge applications, such as the totem-pole bridgeless PFC circuit. It is also well-suited for
resonant DC-DC converters, such as the LLC and phase-shifted full-bridge. As both of these converters utilize
the half-bridge building block, this section will describe how to use the LMG3410 in a half-bridge configuration.
