Switching Regulators & Controllers

Switching Regulators & Controllers

Analog Devices offers a wide range of switching regulators and controllers 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 and controllers 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.

µModule Regulators

Analog Devices’ µModule^® (micromodule) regulators and DC-to-DC power products are complete system-in-package (SiP) power management solutions with integrated DC-to-DC controllers, power transistors, input and output capacitors, compensation components, and inductors within a compact, surface-mount BGA or LGA package. µModule power products support functions such as step-down (buck), step-down and step-up (buck-boost), battery charger, isolated converter, and LED driver. As a highly integrated solution with PCB Gerber files available for every device, µModule power products address time and space constraints while delivering a high efficiency, reliable, and, with select products, a low EMI solution compliant with EN 55022 Class B standards.

Boost Regulators & Controllers

Analog Devices manufactures a broad line of high performance, step-up boost switching regulator ICs and boost switching controller ICs with both synchronous and nonsynchronous switches. These switching voltage regulators offer typical input voltage capability from less than 2 V up to 100 V+, switching frequencies up to 4 MHz, and high efficiency operation up to 96%. With burst mode operation, quiescent currents in the tens of micro-amps level can be attained. This combination of features allows for very small, low profile boost switching regulator circuit implementations with minimum external components. Many of these products can also be configured as SEPIC regulators or flyback topology switching regulators.

Buck Regulators & Controllers

Analog Devices manufactures a broad line of high performance, step-down buck switching regulator ICs and buck switching controller ICs with both synchronous and nonsynchronous switches. These switching voltage regulators offer typical input voltage capability from less than 2 V up to 100 V+, switching frequencies up to 4 MHz, and high efficiency operation up to 96%. With burst mode operation, quiescent currents in the tens of micro-amps level can be attained. This combination of features allows for very small, low profile buck switching regulator circuit implementations with minimum external components.

Buck-Boost Regulators & Controllers

Analog Devices offers true buck/boost synchronous DC-to-DC converters. With their unique internal four MOSFET switch combination, these buck-boost regulators and controllers can seamlessly transition from step-down mode through 100% dropout operation and then to step-up mode to allow a fixed output voltage even when the input voltage fluctuates above or below the output.
