Norwood, MA (07/06/2010) - Analog Devices, Inc. (ADI), a global leader in high-performance semiconductors for signal-processing applications, today introduced the ADP2119 and ADP2120 dc-to-dc switching regulators, the latest in ADI’s portfolio of integrated power management switching regulators. The highly integrated 2A/1.25A, step-down, dc-to-dc synchronous regulators include low on-resistance switching FETs (field-effect transistors) that deliver power conversion efficiencies up to 93 percent. Internal loop compensation and integrated soft-start circuitry are also featured and enable high-density solutions for point-of-load applications. The ADP2119 and ADP2120 accommodate a diversity of point-of-load applications with a 1.2-MHz fixed switching frequency and a wide 2.3-V to 5.5-V operating range. Output voltage is adjustable from 0.6 V to input voltage (VIN), and available in preset output voltage options of 3.3 V, 2.5 V, 1.8 V, 1.5 V, 1.2 V, and 1.0 V. The ADP2119 and ADP2120 regulators are available in small 3 mm x 3 mm LFCSP (lead-frame chip-scale package) packages.
“For the design engineer looking to cost effectively replace less efficient low dropout regulators, the ADP2119 and ADP2120 combined with the availability of online ADIsimPower™ design tools make these regulators very easy to use,” said Martin Ng, product marketing manager, Analog Devices. “Our goal is to address our customers’ power management challenges with products that use less space and reduce their time to market.”

The ADP2119 and ADP2120 regulators and previously announced ADP2118 are well suited for establishing distributed low-noise analog rails to support other Analog Devices components, including the latest generation of ADCs (analog-to-digital converters), amplifiers and DACs (digital-to-analog converters). The fast transient response and ease-of-use make the regulators effective for powering FPGAs and Analog Devices’ Blackfin® and SHARC® processors. ADI’s integrated power management switching regulators are also supported by the ADIsimPower™ design tool, which makes selecting components, simulating power supply performance and building evaluation circuits easy and fast.
