Switching Regulators

Maxim high-efficiency switching regulator ICs provide longer battery life, generate less heat, and require less board space than many competitive products. We provide a wide assortment of DC-DC switching regulators and controllers to handle a broad range of applications.
Maxim's switching regulators contain an internal catch-diode or FET for reduced board space and component count. Our switching controllers are generally used in applications with high power requirements and therefore use an external diode or FET switching elements. You can select a switching regulator or controller from the parametric table below.
