DC/DC converters
Renesas portfolio of DC/DC converters include linear regulators, switching regulators, controllers, PMICs, and power modules. These product families cover a wide range of topologies including buck, boost and buck/boost.
Buck Regulators (Integrated FETs)
Renesas offers a wide portfolio of high-performance buck regulators with integrated FETs. A buck converter, also known as a step-down converter, is a DC/DC power converter that provides voltage step down and current step up. The converter reduces the voltage when the power source has a higher voltage than Vin. A buck converter generally provides the most efficient solution with the smallest external components.
