Printed circuit board (PCB) layout has been an integral aspect of power electronic design since the first switching power supplies appeared more than 40 years ago. Regardless of the transistor technology, the parasitic impedances added to the circuit by the PCB layout must be understood and managed for the circuit to function correctly, reliably, and without causing undue … [Read more...] about Optimizing PCB Layout for HV GaN Power Transistors

Practical Realization of GaN’s Capability
The system-level value of wide bandgap power semiconductors of higher efficiency, smaller size and weight, and more sustainable energy usage in our power supplies and motor drives is being demonstrated now. Gallium nitride (GaN) power FETs are replacing silicon (Si) power MOSFETs in applications from 48 V to 800 V. Silicon carbide (SiC) is replacing legacy IGBTs in applications … [Read more...] about Practical Realization of GaN’s Capability
Expert View: GaN Outperforms Silicon, Enters Mainstream
How does one define ‘main- stream’? In the case of gallium nitride (GaN) power semiconductor technology, we believe that since you can now buy a sleek, 65 W mobile charger using GaN for under $25 on Amazon, it is reasonable to assume that it has been fully accepted by the consumer markets, which—almost by definition—makes it a mainstream product. For more about this … [Read more...] about Expert View: GaN Outperforms Silicon, Enters Mainstream
