AnalogicTech has introduced a family of high voltage, high current, non-synchronous step-down converters capable of providing high efficiency power conversion from 24V supplies. Fabricated in AnalogicTech’s proprietary high voltage Modular BCD process, these new devices offer cost savings for wireless LAN, DSL and cable modem, and set-top box designs by integrating a buck converter with a low noise low dropout regulator (LDO).

By combining two buck converters with a low input voltage used to post-regulate the second buck converter, AnalogicTech’s AAT2782 and AAT2783 are said to extend battery life and reduce board footprint by powering both standard and the lower voltage noise sensitive circuits while maintaining high power efficiency.

By integrating six channels, featuring two buck converters, one with two step dynamic output voltage, with four LDOs, and independent enable functions, AnalogicTech’s AAT2603 power management IC provides designers maximum design flexibility and power up sequencing while offering opportunity to reduce PCB space, improve reliability and reduce cost.

Most smart phones today require some combination of backlight LED drivers for a main display, sometimes additional LED drivers for a smaller sub-display, one or more flash LED drivers, and LDOs to power the embedded camera. By rolling all these functions in various configurations into a single IC, AnalogicTech’s AAT2860 allows designers to minimise component count, board space and cost whether they are building a high end PDA-type phone with a...

AnalogicTech has introduced the AAT2848, a trimode charge pump driver IC for white LED (WLED) backlight display and flash applications. By integrating four backlight channels capable of driving up to 30mA each with two flash channels capable of driving up to 300mA each, or 600mA in parallel, in a small 3mm x 3mm TQFN33-20 package, the device offers mid-range camera phone designers a highly attractive space-saving solution.

The AAT1282 from AnalogicTech is said to be the industry’s first 2A flash LED driver IC capable of delivering high intensity light from white LEDs (WLEDs). Combining a high frequency boost converter with fixed input current limiting, dual output regulated current sinks and I2C control, the device uses a supercapacitor to deliver the high peak current needed to support the high intensity flash required for mobile phones featuring cameras with...

AnalogicTech has introduced the AAT3102 and AAT3103 constant frequency, charge-pump-based, current source white LED (WLED) drivers. Designed to backlight lower-cost LCD displays in entry-level and reduced feature set cell phones, the two new devices help reduce system costs by using a small 2x2.1-mm package while requiring only two external components.

By bringing together a battery charger, a low-noise 300mA buck converter to power the baseband core, five LDOs for all critical digital, analogue, transmit and receive functions, and an I2C interface to control voltages dynamically, AnalogicTech’s AAT2601 allows designers of portable battery powered devices, including those targeted at the Chinese market, to optimise performance, reduce footprint and drive down cost.

Whether building new Portable Navigation Devices (PNDs), Portable Media Players (PMPs) or high-end handsets, today’s system designers must constantly add new features and functions that require higher levels of processing power and more current. By delivering up to 2A at high efficiency in a small solution, AnalogicTech’s AAT1153 step-down converter serves as a key building block in the continual evolution of higher performance yet compact h...

Today many manufacturers of cellular handsets, Bluetooth headsets, MP3 players and other portable systems require over-voltage protection to protect the battery and system against faulty inputs. By integrating an isolated OVP switch, AnalogicTech’s AAT3783 Li-Ion/Polymer battery charger offers protection against single point failures up to 28V while reducing component count and simplifying design.

By taking advantage of lower component profiles, reduced stray inductance, capacitance and resistance and enhanced electrical characteristics, converters using chip scale packaging (CSP) from AnalogicTech enable designers of cell phones, Bluetooth headsets and other space-constrained portable systems to reduce footprint, improve AC performance, and drive down manufacturing costs.

AnalogicTech has introduced two mini-Power Management Units (PMUs) that combine three step-down DC/DC converters in a single monolithic IC. Targeted at portable devices with rapidly evolving feature sets, the 3-channel AAT2784 and AAT2785 allow designers to add one 1.5A synchronous step-down converter and two 300mA synchronous step-down converters or one 1.5A synchronous step-down converter and two 600mA synchronous step-down converters respecti...

AnalogicTech has introduced the AAT1239-1, a high frequency, high efficiency constant current boost converter capable of driving up to10 white LEDs (WLEDs) connected in series. Designed for backlight applications in PNDs, eDictionaries, electronic photo frames and cellular handsets, the new driver IC uses AnalogicTech’s proprietary Simple Serial Control (S2CWire) single-wire interface to dramatically reduce the display flicker that occurs with...

AnalogicTech has introduced the AAT1160, a synchronous step-down DC/DC converter delivering up to 3A output from a 12V input. Combining high power efficiency levels and a very low 150 microamps quiescent current, the AAT1160 offers power savings in a variety of industrial applications, especially those using backplanes, as well as portable systems running off two-cell Lithium-ion batteries.

Designers of digital photo frames, mobile phones, set-top boxes and many other electronic devices typically resort to discrete switches when they need to support more than one power source. By combining two inputs with a low, 200mV dropout in a compact TSOPJW package, AnalogicTech’s AAT4674 and AAT4674-1 offer high system integrity in a smaller, more integrated solution size.

AnalogicTech has introduced the AAT3663, the first in a family of 1A linear battery charger ICs capable of charging up to two Li-ion cells in series. Designed to operate from either an AC adapter or a USB port, the device features AnalogicTech’s innovative Digital Thermal Loop charge reduction circuit that monitors the internal die temperature and gradually steps down the charge current to avoid thermal shutdown.

AnalogicTech has introduced the AAT2847, a highly integrated four-channel White LED (WLED) driver for portable systems operating off a single-cell Li-Ion/Polymer battery. The charge pump-based device also integrates two 200mA Low Dropout (LDO) linear regulators, each with its own independent enable pin, to power ancillary system functions.

AnalogicTech has introduced the AAT2504, an adjustable 3-channel regulator that combines a step-down converter with two low dropout linear regulators (LDOs). Targeted at mobile devices with rapidly changing feature sets, the AAT2504 allows designers to extend system functionality and still benefit from power management integration.

AnalogicTech has introduced a synchronous step-up converter that offers designers extremely high output current in a compact package. Designed to support a wide range of handheld portable applications, the AAT1217 delivers up to 100mA output from a single-cell alkaline battery input, up to 400mA from a dual-cell alkaline battery input and up to 500mA from a single-cell Lithium-Ion battery input while supporting startup as low as 0.85V.
