A DC-DC switching converter is used to locally supply any component or part of a system with the desired DC voltage and current. Depending on the application's relationship between the input and output voltage, engineers have to choose the best power topology – buck, boost, buck-boost or inverting, with or without synchronous rectification. Or they can decide to use an implementation based on monolithic ICs or with discrete power switches and controllers – or even an advanced digital implementation. Whatever their choice, the right semiconductor products are key to meeting their specific efficiency and size design targets.
Boost Converter
In a boost DC-DC converter, the output voltage is higher than the input voltage including in a floating boost topology where the output does not share the reference point with the input. Boost DC-DC topologies are often used in battery-operated equip
View application Buck Converter
A buck or step-down topology is used in DC-DC switching converters where the output voltage is lower than the input with or without input-output isolation.
View application Buck-Boost Converter
In a buck-boost DC-DC converter topology, the output voltage can be higher or lower than the input voltage. Often used in battery-operated equipment, a buck-boost DC-DC converter requires high-efficiency and ultra-low stand-by current as well as a sm
