80V, 98% Efficient, 4-Switch Synchronous Buck-Boost Controller IC with 4 Regulation Loops

Al Wu - Design Engineering Manager Feb 11th 2013
In today’s modern electronic systems, the need for power conversion circuits that can do more then simply convert one voltage to another is growing. Some systems require a constant current, constant voltage output, while others may require a limit on the maximum current that can be drawn from the input. Still others may ...

Small Size and Very High Efficiency Buck-Boost Converter - LTC3780

Henry Zhang - Applications Engineering Manager Jun 15th 2009
Many applications such as battery-powered supply have a wide input voltage that can be lower or higher than the regulated output voltage. The conventional solutions, such as flyback, Sepic or a 2-stage supply are usually complicated and inefficient. The single-stage buck-boost converter only needs a small size inductor with ...
