NX-HB-GAN039-BSC

NX-HB-GAN039-BSC is a 3.5KW half-bridge evaluation board with bottom-side cooled GaN FETs. The NX-HB-GAN039-BSCUL bottom-side cooled half-bridge evaluation board that provides the elements of a simple buck or boost converter. This enables the basic study of the switching characteristics and efficiency achievable with Nexperia’s 650V GaN FETs. The circuit can be configured for synchronous rectification, in either buck or boost mode. Selection jumpers allow the use of a single logic input or separate high/low-level inputs. The high-voltage input and output can operate at up to 400V DC, with a power output of up to 3.5KW dependent upon cooling, ambient temperature and switching frequency. The inductor provided is intended for efficient operation at 100KHz, however, other inductors and frequencies may be used.

• Auxiliary supply range from 10V to 18V
• Logic inputs range from 0V to 5V (nominal)
• Configuration dependent switching frequency
