General Description

The AAT1299 is a high efficiency, synchronous, fixed

frequency, step-up converter with start-up inrush cur-

rent limit and short-circuit protection. The input voltage

ranges from 1.0V to the output voltage.

The high 2MHz switching frequency and completely inte-

grated control circuitry minimize the total solution foot-

print area while maintaining excellent regulation, ripple,

and transient response throughout the full load range.

Light load switching frequency modulation and low qui-

escent current maintain high efficiency performance 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-saving

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.
