AAT1217 Overview
The AAT1217 is a high efficiency, synchronous, fixed frequency, step-up converter designed for single-cell or dual-cell alkaline, NiMH, or NiCd battery-powered applications. The high 1.2MHz switching frequency and pletely integrated control circuitry minimize the total solution footprint area while maintaining excellent regulation, ripple, and transient response throughout the full load range. Light load mode...
