Check out a new feature newly loaded online at ElectronicsWeekly.com - Buck-boost converters change with the timesAs serial-fabric technologies become the limiting factor to system performance, he believes, designers will head to the laboratory and come through with the next-generation high-speed data-delivery system...
Among the points covered by the in-depth article are:
- Buck-boost converters find use in automotive, consumer-electronics, and other applications.
- Simple buck-boost and Cuk converters invert the input voltage.
- SEPICs (single-ended-primary-inductance converters) and four-switch synchronous H-bridge buck-boost converters do not invert the input voltage.
- Many companies are producing synchronous four-switch buck-boost converters for the handheld-system market.
- Most buck-boost architectures have 80 to 85% efficiency, whereas the synchronous-four-switch topology has better-than-92% efficiency.
"Buck-boost converter topologies fit into a wide range of applications. Whether you are charging a battery from a battery, powering a string of LEDs, or running a handheld device from a single cell, the buck-boost topology can provide an important weapon in your arsenal of design tricks. Whether you need low cost, high efficiency, or low noise, some version of buck-boost topology can solve the problem.
"And, if your buck-boost design works for multiple products, you can save yourself the considerable effort of designing separate power supplies for each load voltage. However, as with any type of design, the buck-boost-converter brings its share of design challenges."
