Multitopology DC/DC

Many of Analog Devices’ power management products incorporate one or more switch mode dc-to-dc regulators of different types and topologies. Products in this category offer two or more regulators, combining buck, boost, buck/boost, SEPIC, and/or inverting switching regulators in a single, small package. Some products also incorporate one or more linear regulators as well. Applications for these multitopology products include split positive and negative supplies for high performance op amps and signal conditioning circuitry or combining multiple power supplies into a single, compact IC.
