Our line of step-down voltage regulators makes it easy for designers to meet their system's requirements. With over 200 unique devices, Alpha and Omega Semiconductor offers a wide product portfolio of high-efficiency DC/DC step-down (buck) switching regulators. This family of products includes step-down switching regulators, ranging from 2V to 36V input and featuring 600mA to 30A output.

Our DC/DC step-down (buck) converters integrate with a controller and one or more integrated FETs. Offering a balance of flexibility and ease of use, our synchronous (integrated high-side and low-side FETs) buck converters simplify the design process by reducing external component count. Moreover, we offer design tools that help our customers select an external inductor to further optimize their power supply design for efficiency, solution size, or BOM cost.
