These cores are divided into smaller sections,
reducing the overall resistance and enhancing
performance at high frequencies.
Analog Devices offers gate driver and controller
solutions for GaN that
• Integrate smart bootstrap switches to
prevent overcharging
• Feature near-zero dead-time circuitry to minimize
switching losses
• Have separate pull-up and pull-down circuits to
deliver precise control over the gate voltage
Bourns offers magnetics solutions for GaN that
• Incorporate advanced magnetic materials like high-
permeability ferrites and nanocrystalline alloys to
reduce core losses at high frequencies
• Utilize segmented ferrite technology to minimize
core and fringing losses to improve efficiency
• Are customized to handle the higher current
densities and elevated switching frequencies
characteristic of GaN technology
• Leverage optimized winding techniques to
reduce copper losses
GaN's ability to operate at
higher temperatures and
frequencies presents unique
thermal management
challenges. Effective heat
dissipation and careful
selection of core materials are
essential to minimize losses
and ensure reliable operation in
high-power applications."
