Power Management IC streamlines mobile GPS, PMP designs.July 11, 2008 -
Supplied in 4 x 4 mm TQFN package, AAT2603 integrates 6 power functions - 2 buck converters and 4 LDOs - with independent enable pin for each. IC operates from 2.7-5.5 V input and is suited for handheld mobile systems operating off one lithium-ion battery. Delivering with 200 mV of head room, first step-down converter supports functions requiring high output current and low dropout voltage. Second step-down converter supplies 600 mA and adds 2-step dynamic output voltage capability.

AnalogicTech's New Power Management IC Streamlines Mobile GPS, PMP Designs
6 Channel PMIC integrates Two Buck Converters and Four LDOs into 4x4 TQFN package
SANTA CLARA, Calif., July 8 -- Advanced Analogic Technologies, Inc. (AnalogicTech) (NASDAQ:AATI), a developer of power management semiconductors for mobile consumer electronic devices, announced today the AAT2603, a new highly integrated power management IC targeted at mobile GPS devices, Portable Media Players (PMPs) and other handheld mobile systems operating off a single lithium-ion battery. Offering maximum design flexibility, the new device integrates six power functions, including two step-down converters and four LDOs, each with its own independent enable pin, in a small 4x4-mm TDFN package.
"Today's Portable GPS devices and PMPs demand an increasingly wide array of power functions as they extend their feature sets," said Siamak Bastami, product line director for AnalogicTech. "By integrating 6 channels, featuring two buck converters, one with two step dynamic output voltage, with four LDOs, and independent enable functions, the AAT2603 provides designers maximum design flexibility and power up sequencing while offering opportunity to reduce PCB space, improve reliability and reduce cost."
Focus on independent control
The AAT2603 operates off a 2.7V to 5.5V input range and offers high efficiency across the entire load range. Delivering with only 200mV of head room, the first step-down converter supports functions requiring high output current and low dropout voltage. The second step-down converter supplies 600mA and adds a two-step dynamic output voltage capability to match the needs of common system processors. The converter dynamically shifts between the two output voltages by toggling the SELB2 pin.
Four LDOs supply power to a variety of system functions. Two LDOs deliver 200 mA and are designed to power noise sensitive circuits. The second pair of LDOs offers 400 mA output. Each of the four LDOs consumes just 50 uA of quiescent current.
The new IC also features multiple protection circuits including those for short-circuit, over-current and over-temperature protection.
Price and Availability
The AAT2603 is qualified across the -40 degrees C to +85 degrees C temperature range. It is available in a Pb-free, 28-pin, 4x4-mm TQFN package. The device sells for $1.64 in 1K quantities.
