The NX-HB3500EV half-bridge evaluation board by NXP 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 650 V 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 400 V DC, with a power output of up to 3.5 kW. The inductor provided is intended for efficient operation at 100 kHz, however, other inductors and frequencies may be used.
