General Description
The AAT1265 is designed for single-cell or dual-cell alkaline, NiMH, or NiCd or single-cell lithium-ion/polymer (Li-Ion) battery-powered applications. It is a high efficiency, synchronous, fixed frequency, step-up converter with true output disconnect during shutdown (<1.0μA), start-up inrush current limit, and short-circuit protection. 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 performance for light load and sleep m……
