Step-down (buck) switching regulators

Efficient conversion of an input voltage to a lower output voltage

With over 1000 unique devices, we own the industry’s most comprehensive portfolio of high-efficiency DC/DC step-down (buck) switching regulators. This extensive family of products includes all types of switching regulator, ranging from the flexibility of a controller IC to the high-integration and simplicity of a buck power module. From 1V to 100V input and 50mA to 420A output, you can count on us to have a buck voltage regulator that meets your system’s requirements. 

Power module

We have the industry's largest and most diverse portfolio of DC/DC buck modules. With integrated FETs and inductor, power modules simplify your power supply design process and get you to market faster.


We have a comprehensive portfolio of synchronous and non-synchronous DC/DC buck converters spanning 1.3V to 100V and 50mA to 40A. With an integrated FET or FETs and external inductor, converters provide a good balance of integration and flexibility.


Our family of DC/DC buck controllers extends to 100V maximum input voltage and 420A maximum output current. Controllers with external FETs and inductor provide the most design flexibility for high-power applications.
