High Step-Down Ratio Buck Converters With eGaN Devices

The intermediate bus architecture (IBA) is currently the most popular power system architecture in computing and telecommunications equipment. It typically consists of a +48 V system power distribution bus that feeds on-board bus converters, which in turn supply power to nonisolated, dc-dc converters. These nonisolated converters generate the low supply voltages required to power the various logic circuits. Because of their proximity to the circuits they power, these converters are commonly referred to as point-of-load converters (POLs). By Johan Strydom, EPC, El Segundo, Calif. and Bob ... Read more

Driving eGaN™ FETs Both gate and Miller capacitances are significantly lower

As enhancement mode gallium-nitride-on-silicon transistors (eGaN™) gain wider acceptance as the successor to the venerable - but aged - power MOSFET, designers have been able to improve power conversion efficiency, size, and cost. eGaN FETs, however, are based on a relatively new and immature technology with limited design infrastructure to quickly design and implement products.
