General Description

The AAT1299 is a high efficiency, synchronous,

fixed frequency, step-up converter with start-up

inrush current limit and short-circuit protection. The

input voltage ranges from 1.0V to the output voltage.

The high 2MHz switching frequency and completely

integrated control circuitry minimize the total solution

footprint area while maintaining excellent regulation,

ripple, and transient response throughout the full

load range.

Light load switching frequency modulation and low

quiescent current maintain high efficiency perform-

ance for light load and sleep mode conditions.

With a 1A peak switch current limit, the AAT1299 is

capable of delivering 200mA to the load from a

1.8V input.

The AAT1299 is available in a Pb-free, space-sav-

ing 2.0x2.1mm 8-pin SC70JW or 2.2x2.2mm 10-

pin STDFN package, or in die form and is rated

over the -40°C to +85°C temperature range.
