Renesas has many options for DC/DC converters, controllers and regulators with buck, boost and buck-boost topologies.
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.
Unsure if a low-powered linear regulator or highly efficient switching regulator is a better option for your design? Learn more about Linear vs. Switching Regulators.
Boost converters, also known as step-up converters, are DC/DC power converters with an output voltage greater than its input voltage. The driver boosts the voltage of the power source that is less than the Vin.
A buck-boost converter generates an output voltage either greater or less than the input voltage. The advantage of using a buck-boost solution is regulating the output voltage over the full power source voltage range. Buck-boost converter solutions usually have lower efficiency and a larger footprint than buck converter solutions.
