Infineon is pushing vertical power delivery with its next generation of multiphase DC-DC converters, which are small enough to be tucked underneath GPUs and other power-hungry SoCs.
Multimegahertz buck converters require higher-frequency operation than silicon power transistors can provide. To meet this need, gallium nitride (GaN) power transistors enable higher efficiency and higher speeds.
With a good company, you’re buying much more than the chip. You’re also obtaining the confidence that the chip was in good hands, because it’s usually designed by experts in the industry.
What’s the better option: a single-phase controller design or two converters interleaved in a dual-phase design? This article shares insight into the design considerations and tradeoffs between the two solutions.
