LT8418 Overview
The LT8418 is a 100V half-bridge GaN driver that integrates top and bottom driver stages, driver logic control, and protections. It can be configured into synchronous half-bridge, full-bridge topologies, or buck, boost, and buck-boost topologies. The LT8418 provides strong current sourcing/sinking capability with 0.6Ω pull-up and 0.2Ω pull-down resistance.
