Advanced Analogic Technologies Incorporated (AnalogicTech) and Siliconix, a subsidiary of Vishay Intertechnology Inc. (NYSE: VSH), have reached an amicable settlement of the patent infringement lawsuit brought by Siliconix in the United States District Court for the Northern District of California. The lawsuit, filed in January 2004, related to alleged infringement of three U.S. patents pertaining to trench DMOS technology.

AnalogicTech has signed a product distribution agreement with Mouser Electronics, the broad-line catalogue distributor. Through its online and print catalogues, Mouser will offer selected AnalogicTech power management products in the Americas, Europe, the Middle East, and Africa. Mouser will market most AnalogicTech products, including newly introduced devices and they will be available in small quantities.

AnalogicTech has introduced the AAT2554, the industry’s first power management IC to combine a 500mA battery charger, 250mA step-down converter, and 300mA low dropout (LDO) linear regulator in a tiny 3x4mm package. Part of AnalogicTech’s rapidly expanding SystemPower product family, this multi-function device offers designers of ultra-low-power products a highly compact power management solution that reduces product footprint and design comp...

AnalogicTech has announced that it has entered into a definitive agreement to acquire the power management analogue business of IPCore Technologies Corporation, including IPCore’s subsidiary Analogue Power Semiconductor Corporation (AP Semi) and certain related assets.

Rated at 24V at 100mA, the AAT1232 is the latest addition to AnalogicTech’s rapidly growing family of boost converters targeted primarily at cost-sensitive OLED, LCD, and CCD applications. The device offers substantial output drive capability in an extremely compact footprint. Operating at a switching frequency up to 2MHz, the AAT1232 reduces PCB footprint by using small-value external inductors and capacitors. For example, the device operate...

AnalogicTech has introduced the AAT1142, a voltage-scaling step-down converter for portable applications. Supplying up to 800mA output current, the device is said to be the first voltage-scaling step-down converter to offer dynamic voltage management through both a two-wire I2C interface and AnalogicTech’s patented single-wire Simple Serial Control digital interface.

By utilising AnalogicTech’s AAT1231, designers can use a single wire to digitally control white LEDs, giving flicker-free light output, reduced MCU clock cycles, a saving of GPIO resources, and providing a complete solution for portable applications that uses fewer components.

AnalogicTech has introduced the AAT1171, a fully integrated voltage-scaling DC/DC step-down converter specifically optimised to control the power to the power amplifier in WCDMA and CDMA handsets. By dynamically controlling the operating voltage of the PA in mobile phones, the AAT1171 increases amplifier efficiency and extends talk time.

The power supply supporting a GSM handset baseband chipset must wake up to full load within microseconds. By integrating a fast transient 600mA step-down converter and a 300mA LDO, AnalogicTech’s AAT2505 forms a complete high-performance power supply solution for GSM handset baseband core and I/O.

Ultraportable systems running from single or dual alkaline, NiMH, or NiCd cells need to boost voltage while conforming to strict requirements for battery life and system size. A low-voltage step-up converter from AnalogicTech maintains high efficiency over the entire output current range, requires no external compensation, and provides true load disconnect (TLD) ­ all in a tiny 2.0x2.1mm SC70JW package.

By mounting an 800mA converter in a tiny SC70JW package, AnalogicTech¹s AAT1110 delivers the higher current that these new designs require yet still enables the smallest solution size possible. The AAT1110 is the industry¹s first 800mA step-down DC/DC converter in a tiny 2.0x2.1mm SC70JW package.

The AAT3681 from AnalogicTech is an extremely small, single-cell Lithium-ion/polymer battery charger IC designed to operate from either a USB or an AC adapter on the same input. This latest addition to AnalogicTech¹s rapidly growing battery charger IC product line supports the latest generation of space-constrained ultra-portable applications by supplying up to 300mA in a tiny SC70JW package.

Advanced Analogic Technologies Incorporated (AnalogicTech), a developer of power management semiconductors for mobile consumer electronic devices, and Vanguard International Semiconductor Corporation (VIS), a leading specialty IC foundry service provider, have announced plans to integrate AnalogicTech’s 0.35micron multi-voltage mixed-signal ModularBCD process technology into VIS’ advanced 200mm submicron fabrication facilities in Taiwan.

Advanced Analogic Technologies Incorporated (AnalogicTech) has announced the AAT1121, a step-down converter for extremely space-constrained portable applications. Mounted in a tiny TDFN package, the device offers 250mA output current at up to 96% efficiency.

By offering hysteretic control and high stability while minimising leakage current losses, AnalogicTech’s AAT1230 is the ideal application-specific power solution for OLED modules.

AnalogicTech has introduced a high current, high efficiency charge pump for multi-function LED applications. Recognising that a serial bus is a powerful tool for driving LEDs, the AAT3174 helps designers who want to quickly and easily develop a solution that supports both flash and movie mode operation and, importantly, can move between the two modes using a simple on/off toggle switch.

To generate the three colours in an RGB LED, designers would typically need to use three separate MOSFETs, all the associated interface circuitry, and three GPIO pins on the system processor to drive the RGB LED. With AnalogicTech’s AAT4295 and AAT4297, designers can now support up to two RGB LEDs while eliminating the need for discrete MOSFETs and save the GPIO lines for other system functions.
