Switching Regulators

Analog Devices offers a wide range of switching regulators that operate in step up (boost), step down (buck), and inverting modes. These devices are capable of generating a fixed or adjustable output voltage, and offer up to 2A of output current. Some of the features available in ADI’s portfolio of switching regulators are low battery detector, user adjustable current limit, a variety of switching frequencies, and a reduced number of external components.This highly integrated, versatile family of products is intended to minimize external components for space challenged applications.
