　　The block diagram of the half-bridge circuit design， shown in Figure 2， consists of two eGaN FETs， a driver integrated circuit （IC）， pulse width modulation （PWM） logic， dead-time adjust， and high-frequency input capacitors. The design and layout of these components is critical to fully utilize the high-speed capability of the eGaN FET technology. The DrGaNPLUS gate-drive circuitry ensures the gate-drive requirements for eGaN FETs are met and provides optimized performance with the latest GaN driver IC technology. Users can input two PWM signals to individually control the devices or use the on board logic and dead-time adjust circuit to input a single PWM signal and obtain an optimized dead-time for a buck converter application to maximize performance. The high-frequency input capacitors， also located on board， are arranged with the two eGaN FETs in an optimized PCB layout， minimizing the common source inductance and the high-frequency power commutation loop inductance to decrease switching losses and voltage overshoot. The DrGaNPLUS eliminates complexity and provides the designer an easy-to-use optimized solution with available pads to mount to the PCB， shown on the right in Figure 1.
