AAT1299

AAT1299 Low Voltage 2MHz Step-Up DC/DC Converter 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, www.DataSheet4U.com ripple, and transient response throughout the full load range. Light load switching frequency modulation and low quiescent 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 10pin STDFN package, or in die form and is rated over the -40°C to +85°C temperature range.
