Hybrid Buck Converter

About

Invention In this modern era, a high efficient buck converter is a vital component in all the battery-powered devices.  As the technology is advancing, integrated system on-chip designs are developing, which needs fast transient response to fit the demands of SOC. The invention of hybrid buck converter provides fast transient response with seamless loop transition automatically. Moreover, during steady state of hybrid buck converter, the auxiliary linear regulators can be deactivated automatically. The effective part of auxiliary linear regulators is only very little increment in area compared with whole converter block. Thus it is extremely suitable for power management portable devices. Marketing Opportunity Any devices which needs buck converter to regulate their battery voltage to a specific voltage should definitely use this technique. Efficiency and fast response circuitry are the core needs for any power management devices; the unique feature of this invention will allow the product to have more steady supply under the fast switching environment, which is extremely important for advanced computing function and power management of the modern processor for their increment on functionality. Any devices, such as smartphone, flat panel computer, notebook and so on, which need very specific voltage to work on, should go for this. Key Benefits Buck converters with fast transient-responses. Auxiliary linear regulators on activated during transient change and will automatically disable in steady state, efficiency has been increased. Seamless loop transition automatically. Simple but effective design, easy for short time-to-market
