The LMG3522R050 is a power IC targeting hard-switching and soft-switching applications operating up to 520-V bus voltages. GaN devices offer zero reverse-recovery charge enabling high-frequency, hard-switching in applications like the totem-pole PFC. Low Q_oss of GaN devices also benefits soft-switching converters, such as the LLC and phase-shifted full-bridge configurations. As half-bridge configurations are the foundation of the two mentioned applications and many others, this section describes how to use the LMG3522R050 in a half-bridge configuration.
