GaN Systems Inc of Ottawa, Ontario, Canada (a fabless developer of gallium nitride-based power switching semiconductors for power conversion and control applications) has announced availability of its GS61008P-EVBHF 5MHz buck converter evaluation board, which uses GaN Systems’ 100V enhancement-mode (E-mode) GaN transistor and the PE29101 integrated high-speed driver of pSemi of San Diego, CA, USA. The outputs of the pSemi driver can provide switching transition speeds in the sub-nanosecond range.
The evaluation board allows the benefit of higher switching speeds, enabling smaller peripheral components in a variety of applications including DC–DC conversion, AC–DC conversion, wireless power charging, and LiDAR.
“GaN has a robust ecosystem of quality partners like pSemi,” says Peter Di Maso, director, product line management at GaN Systems. “Working with pSemi, we’ve been able bring faster switching, higher frequencies and higher-power-density solutions to customers. These benefits come together to reduce power losses, size, weight and system costs.”
GaN E-HEMTs exhibit much higher efficiencies than MOSFETs and exceed performance in terms of switching speed, parasitic capacitance, switching loss, and thermal characteristics, says GaN Systems. The evaluation board highlights the high-frequency, high-speed, and high-efficiency performance of the firm’s products.
The GS61008P-EVBHF is being showcased in booth #1041 at the Applied Power Electronics Conference & Exposition (APEC 2018) in San Antonio, TX, USA.
