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 2 A 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.
