WD1039EB High Efficiency 2A continuous, 2.5A peak, 1MHz Synchronous Step Down Regulator WD1039EB Http//:www.sh-willsemi.com Descriptions The WD1039EB is a high efficiency, synchronous step down DC-DC convertor optimized for battery powered portable applications. It supports up to 2A continuous 2.5A peak output current. With a wide input voltage range of 2.7V to 5.5V, the device supports applications powered by single Li-ion battery with extended voltage range, two and three alkaline cell, 3.3V and 5V input voltage range. The WD1039EB operates at 1MHz fixed switching frequency with Pulse-Width-Modulation (PWM) and enters Pulse-Skipping-Modulation (PSM) operation at light load current to maintain high efficiency over the entire load current range.
