Energy Harvesting

Analog Devices offers a wide range of ultra low power ICs for energy harvesting applications. Power management products that convert energy from vibration (piezoelectric), photovoltaic (solar), and thermal (TEC, TEG, thermopiles, thermocouples) sources provide high efficiency conversion to regulated voltages or to charge batteries and super capacitor storage elements. Boost converters that operate from as little as 20 mV or battery chargers with maximum power point capability expand the possibilities for industrial automation and control, wireless sensor, transportation, automotive, and building management applications. Ultra low quiescent current linear regulators, op amps, comparators, voltage supervisors, ADCs, DACs, and micropower voltage references provide additional building blocks for autonomous systems.

Inductorless (Charge Pump) DC/DC Converters

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.

This enables designers to implement isolation in designs without the cost, size, power, performance, and reliability constraints found with optocouplers. With more than one billion channels shipped into the field, these magnetically isolated products are a safe, reliable and easy-to-use alternative to optocouplers.

LDO Linear Regulators

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.

LED Driver IC

Analog Devices has a very broad line of LED driver ICs for automotive, display backlighting, handheld, and general high-power lighting applications. They are configured as either inductorless (charge pump) or switching regulator-based LED drivers that support driving white LEDs in series, parallel or combination. Topologies include boost regulator, buck regulator, buck/boost, SEPIC topology LED drivers, and more. Regardless of topology, these ICs offer the highest efficiency, lowest noise, and the smallest footprints.

PMIC and Multifunction

Many of Analog Devices’ battery management products combine the functionality of our standalone battery chargers with one or more other functions. Our power management IC (PMIC) products combine battery charging, PowerPath control, and one or more dc-to-dc regulators for a complete power solution for handheld products. Our PowerPath products and architecture allow the load to be powered from both V_IN and the battery—ensuring shorter charging time and more flexibility for portable device design. They also enable instant-on in systems with a depleted battery. Other features include dual inputs for USB and wall adapters, switching regulators, comparators, or LDOs.

Smart Power Stages (FET and FET Driver)

Analog Devices’ growing portfolio of SilentMOS™ smart power stages provide an unrivaled integrated solution to optimize power efficiency, transient performance, and reduce EMI/EMC. Fully integrated high-speed gate drivers coupled with low resistance half-bridge power switches are augmented with accurate switch current and thermal monitoring telemetry. Combined with a suitable high frequency controller, this smart power stage forms a compact, high current voltage regulator system with state-of-the-art efficiency and transient response. SilentMOS technology utilizes second generation Silent Switcher^® 2 architecture reducing both EMI and switch-node voltage overshoot while maximizing efficiency at high switching frequencies.

Supercapacitor Chargers

Analog Devices offers a portfolio of supercapacitor charger ICs designed to charge supercapacitors (also known as ultracapacitors). These supercapacitor charger devices come in both linear and switching topologies and offer input or output current limiting, automatic cell balancing, and a range of protection features that make them uniquely suited to supercap charging. Due to the number of advantages supercapacitors have, such as lower effective series resistance (ESR) and enhanced durability in the face of repeated charging, they are an increasingly important alternative to batteries in applications where the importance of power delivery trumps that of total energy storage.

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.

Ultralow Noise Regulators

Analog Devices offers a specialized family of ultralow-noise linear and switching regulators designed for applications with stringent noise requirements, such as sensitive RF or audio circuits in confined environments. This product family features a unity-gain current reference architecture that delivers a fast transient response and a high Power Supply Rejection Ratio (PSRR). The Silent Switcher 3 regulators are available in step-down topologies and can also be configured in inverted buck-boost (IBB) mode to power negative rails while maintaining exceptional low-noise performance. Ultralow-noise LDOs (low-dropout linear regulators) provide extremely low dropout, fast transient response, and excellent line and load regulation. Output voltages for both the switchers and LDOs can be dynamically adjusted by applying a DAC to the SET pin. The integrated RMS noise, measured from 10 Hz to 100 kHz, for these ultralow noise linear and switching regulators, is typically in the range of tens of microvolts or lower.

Xenon Photoflash Charger

Analog Devices’ growing portfolio of photoflash chargers provides effective and low profile solutions to trigger a xenon flashlamp. These monolithic switching regulator chargers have current ratings from 225 mA to 2 A, can operate from input voltages as low as 1.8 V, are packaged in MSOP or ThinSOT packages, and require very tiny transformers—charging a 220 μF capacitor to 320 V from 5 V in as little as 3.7 seconds.
