Overview
600mA, 1.
2MHz, Micropower Synchronous Step-Up Converter General Description Features AAT1217 SwitchReg™ www.
DataSheet4U.
com The AAT1217 a high efficiency, synchronous, fixed frequency, step-up converter designed for singlecell or dual-cell alkaline, NiMH, or NiCd batterypowered applications.
The high 1.
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.
• • • • • • • The AAT1217 is available in a Pb-free, space-saving low profile (1mm) 6-pin TSOT23 package and is rated over the -40°C to +85°C ambient temperature range.
Pulse skipping mode operation and low quiescent current allow the AAT1217 to maintain high efficiency performance for light load and sleep mode conditions.
With a 1.
2A peak switch current limit, the AAT1217 is capable of delivering 100mA to the load from a single AA cell or up to 400mA from dual AA cells...
