Analog Devices’ family of charge pumps offers the widest selection of simple and compact inductorless dc-to-dc converter designs. These converters can be used to step-up, step-down, or invert an input voltage. By eliminating the inductor, these switched capacitor converters provide a small solution footprint and a simpler design. Furthermore, by incorporating spread spectrum technology on-chip, both input and output noise are significantly reduced.

Analog Devices’ circuit monitors deliver precise, board-level measurements along with comprehensive monitoring of current, voltage, power, charge, and time. Featuring integrated 12-bit analog-to-digital converters (ADCs) and internal accumulators, they support rails up to 100 V and currents up to ±30 A, with high dynamic range and <±0.8% accuracy. Additional capabilities include internal or external time base options, parametric measurements, and integrated sense resistor monitoring—enabling complete and efficient system-level circuit analysis.

Analog Devices’ fan and thermoelectric cooler (TEC) controllers provide comprehensive cooling solutions for regulating fan speed and thermoelectric cooling. Fan speed controllers utilize a 2-wire SMBus/I²C interface to adjust fan speeds according to the system's temperature profile, resulting in reduced power consumption, extended battery life, and minimized noise compared to simple on-off fan control systems. TEC controllers are designed for cooler-based photonics, offering compact size, high efficiency, and robust performance. They feature both linear and pulse width modulation power stages, with options for digital or analog PID control. These TEC controllers support various MSA-based optical modules, including SFP, SFP+, QSFP+, CFP/CFP-2/CFP-4, and QSFP28.

Analog Devices manufactures a broad line of high performance low dropout (LDO) linear regulators. These LDO linear regulators offer very low dropout, fast transient response, and excellent line and load regulation, features that add performance value to end applications in Wired/Wireless and Audio Systems, FPGA/DSP/µC Power, and RF and instrumentation. The wide selection of our LDO Linear Regulators offer a great variety of features that meet your need in any design, whether it's low noise, high PSRR, or compact packaging.

MOSFET and gate drivers are integral components in power management, power conversion, and motor control applications, serving as the interface between controllers and power stages. These drivers convert low voltage logic signals from controllers into robust gate drives for various power devices. Analog Devices offers an extensive portfolio of high-side, low-side, and half-bridge gate drivers, supporting numerous topologies and voltage ratings. Utilizing ADI MOSFET and gate drivers provides several advantages, including simplified layout, enhanced system protection, customizable turn-on/off profiles, optimized efficiency, improved thermal management, and reduced electromagnetic interference.

A power management integrated circuit (PMIC) is a highly integrated device with many functional circuit blocks onboard. The high level of integration provides many benefits, including reduced printed circuit board (PCB) space, simpler design, faster time to market, and a reduced bill of material (BoM) cost. Analog Devices’ PMICs with battery chargers or USB power managers address battery charging and provide multiple system rails in portable products, all in a compact form factor. PowerPath control allows for seamless transitions and manages power flow between different input sources such as a wall adapter, USB port, and lithium battery while preferentially providing power to the system load.

Analog Devices’ power system management (PSM) ICs and sequencers allow you to keep existing analog power systems while adding new capabilities: output trimming (±0.25% precision), margining, sequencing, nonvolatile fault recording, and digital monitoring data (on voltage, current, power, energy, temperature, and faults). Our portfolio spans a wide range of channel counts (2 to 16 supplies) and easily manages even larger POL power systems found in network routers and switches, servers, enterprise data storage systems, and automated test equipment. This portfolio uses digital I2C/SMBus interfaces, LTpowerPlay® software, and internal EEPROM with several customization options.

Analog Devices offers a comprehensive portfolio of robust protection solutions—including surge stoppers, hot swap controllers, USB power switches, and ideal diode controllers—that safeguard systems against overvoltage, overcurrent, reverse polarity, and transient surges. Designed to meet demanding automotive, military, and avionics standards, these compact, easy-to-integrate protection switches and controllers enhance system reliability and uptime across a wide range of applications, from server racks and industrial systems to portable electronics and automotive platforms. With patented power monitoring, precise current limiting, and intelligent PowerPath control, our protection ICs optimize performance, size, and cost while ensuring uninterrupted operation under fault conditions.
