VisIC GaN evaluation board

VisIC Technologies, a technology-leading developer of Gallium Nitride power semiconductors, previously announced the world’s lowest resistance 650V blocking voltage ALL-Switch product family specifying an Rdson as low as 15 mOhm.

VisIC Technologies has now delivered ALL-Switch Evaluation Boards (EB) and samples to leading customers. The EB allows customers to perform extensive testing confirming ALL-Switch’s leadership switching parameters.

The EB includes gate driver and switching control logic based upon commercially available components. ALL-Switch is configured for hard switching on the EB and can switch a 400V load with greater than 30A currents at over 500kHz. (See the attached oscilloscope trace.)

Meeting the highly demanding requirements of power switching with GaN has been the Holy Grail for power conversion research in the last decade. ALL-Switch is a product realization of that research.

VisIC’s technology solves problems that have limited devices from simultaneously achieving step function reductions in conduction and switching losses for power conversion systems that can benefit from high switching speeds.  VisIC’s products easily exceed the performance of competitive products using Silicon, Silicon Carbide or GaN.

VisIC will soon announce soon the details of a Half Bridge reference design.
