WebFeb 21, 2016 · The switch-node ringing happens in a buck converter when the high-side switch, QH1, turns on. As the LDRV1 turns off, the inductor current starts flowing in the body diode of QL1. When the high-side gate driver, HDRV1, starts turning on QH1, inductor current starts to transition from the low-side body diode to the high-side switch. WebApr 13, 2024 · Figure 3 shows the block diagram of the proposed GaN synchronous DC-DC buck converter with DTG. It integrates a deadtime generation circuit, gate driver circuits, and a half-bridge power stage. The bootstrap diode D BT and the bootstrap capacitor C BT provide a floating DC power supply when the switching node V S varies from 0 to V …
