Cambridge GaN Devices (CGD) has developed a range of interface boards that allow designers to use its integrated ICeGaN devices in existing GaN and MOSFET circuits without having to re-design a board.

The Application Interface Boards are adaptor PCBs that are soldered to an ICeGaN device, which map each pin/signal from the ICeGaN HEMT footprint to the corresponding pins/signals of an alternative component footprint.

The initial 12 boards are designed for sockets for GaN devices from Infineon, Navitas, GaN Systems, and Innoscience as well as a CoolMOS silicon MOSFET from Infineon.

“These Application Interface Boards are designed for design and evaluation purposes only, of course,” said Peter Comiskey, director of applications engineering at CGD.

“This is a quick, first step to enable the user to put one of our ICeGaN ICs into an existing design. There is some minor impact on thermal performance, but surprisingly little difference in EMC or electrical performance.”

The company says it is happy to develop an Application Interface Board for devices not currently supported for delivery within four weeks.; The user guide and list of parts is at
