Navitas Var GaN Boards

Navitas Semiconductor is a revolutionary force in power electronics. They design and manufacture next-generation power semiconductor components, specifically Gallium Nitride (GaN) based integrated circuits (ICs). These GaNFast™ power ICs integrate GaN power and drive functionality along with control, sensing, and protection. This innovative approach enables significant advancements in power conversion, resulting in faster charging times, higher power density in devices (leading to smaller form factors), and overall greater energy efficiency in power supplies. Their target applications range from everyday consumer electronics chargers to data centers, solar inverters, and even electric vehicles.

Key Demos & Products 

33W Flyback Power Board

• This is a low-power DC-DC converter board likely used for powering small electronics like laptops, tablets, or phone chargers. It utilizes a flyback converter, a type of circuit that efficiently steps down a DC voltage level. Flyback converters are known for their simplicity and compactness, making them ideal for low-power applications.

240W Totem Pole LLC Power Board

• This is a higher-power AC-DC converter board designed for applications demanding more power, potentially powering devices like gaming consoles, desktop PCs, or even some industrial equipment. It employs a more complex design with two key components:
  • Totem Pole PFC (Power Factor Correction): This stage efficiently converts incoming AC mains into a DC link voltage with a high cosPhi and low THD.
  • LLC resonant converter: This stage takes the DC output from the PFC and transforms it to the desired voltage level for the final application, doing so with high efficiency thanks to its resonant mode of operation.

3Phase BLDC Motor Driver Board

• This high voltage BLDC motor inverter board uses GaN switchers from Navitas to ensure a fast switching and a low loss commutation to minimize losses in the inverter and so shrinking the size of the inverter. This approach can be used in automotive, industrial and consumer motor inverters that have ideally a link voltage higher than 300V. This can be a fan, pump or robot application.
