Power IC sports two convertors and four LDOs

The highly integrated AAT2603 comes in a small 4 x 4mm TDFN package.

The AAT2603 is a 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 highly integrated device comes in a small 4 x 4mm TDFN package.

The AAT2603 operates off a 2.7 to 5.5V input range and offers high efficiency across the entire load range.

Delivering with only 200mV of headroom, the first step-down convertor supports functions requiring high output current and low dropout voltage.

The second step-down convertor supplies 600mA and adds a two-step dynamic output voltage capability to match the needs of common system processors.

Four LDOs supply power to a variety of system functions.

Two LDOs deliver 200mA and are designed to power noise sensitive circuits.

The second pair of LDOs offers 400mA output.

Each of the four LDOs consumes just 50uA of quiescent current.

The IC also features multiple protection circuits including those for short-circuit, overcurrent and overtemperature protection.

The AAT2603 is qualified across the -40 to +85C temperature range.

It is available in a Pb-free, 28-pin, 4x4-mm TQFN package.
