Power Management
Analog Devices’ Power by Linear™ power management ICs and power modules provide the foundation for powering today’s and tomorrow’s innovations across all markets. Our high performance power management solutions meet stringent power requirements with leading-edge design and packaging technologies, including unmatched power densities, ultralow noise technology, and superior reliability. These features ensure systems operate at their optimal efficiency, speed, and power levels, while increasing feature density and reducing cost of ownership. Supported by the industry’s most comprehensive start-to-finish power design tool suite, along with highly configurable power interconnect solutions, ADI’s low complexity power management solutions help our customers accelerate time-to-market while delivering best-in-class performance.
Silent Switcher®: High Efficiency, Low EMI
Silent Switchers from ADI offer high efficiency at high switching frequencies while maintaining ultralow EMI emissions, and the newest addition to the Silent Switcher family adds unrivaled ease-of-use: The LT8650S delivers a compact dual-output 4A synchronous step-down solution that is up to 95% efficient at 2MHz while easily passing the CISPR 25 class 5 peak EMI limits. View the product line and get full specifications on our Silent Switcher page.
Fast Simulation with LTspice®
This free, high performance SPICE simulator, schematic capture, and waveform viewer features enhancements and models for easing the simulation of switching regulators.
μModule Design and Manufacturing
A µModule® power product simplifies implementation, Verification, and Manufacturing of complex power circuits by integrating the power function in a compact molded plastic package.
Power Management Tools
LTspice® is a high performance SPICE simulation software, schematic capture and waveform viewer with enhancements and models for easing the simulation of analog circuits. Included in the download of LTspice are macromodels for a majority of Analog Devices switching regulators, amplifiers, as well as a library of devices for general circuit simulation.
LTpowerPlay® is a powerful development environment supporting the Power System Management (PSM) products of Analog Devices, including PMBus Power System Managers and DC/DC Power Converters with PSM. The software supports a variety of different tasks, including an offline mode (with no hardware present) in order to build a multi-chip configuration file that can be saved and reloaded at a later time.
The LTpowerCAD® design tool is a complete power supply design tool program that can significantly ease the tasks of power supply design and provides recommendations for component values and performance estimates specific to the user’s application with the μModule and monolithic DC/DC regulator products of Analog Devices. This guides the user through the entire design process reducing design effort and speeding up design time.
