Keynote 1: Is GaN a Game Changing Device ?

Abstract

Gallium Nitride devices are gathering momentum, with a number of recent market introductions for such applications as point of load converters (POL), off-line switching power supplies, battery chargers and motor drives. GaN devices have a much lower gate charge and lower output capacitance and, therefore, are capable of operating at a switching frequency 10 times of that of the silicon MOSFET. This might significantly impact the power density, form factor and even the current design and manufacturing practice.
