To operate these devices, highly efficient and high power density, compact, current regulated switching converters are necessary. In this paper, Gallium Nitride (GaN) based synchronous buck converters are studied for the application of laser diode driver. For this purpose, two synchronous buck converters one with Si-based the other one with GaN-based are designed, simulated, tested and compared. With the application of GaN-based semiconductors, 96.6% efficiency and 9.1 W/cm <sup>3 </sup> power density is achieved for 11A, 28V load at 700 kHz operating frequency.  </span> <br> </p>}, number={1}, publisher={MUSA YILMAZ}
