ADVANCE INFORMATION for pre-production products; subject to change without notice.
The LMG341xR050 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 LMG341xR050 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 LMG341xR050 in a half-bridge configuration.
