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. 100%
duty cycle capability provides low dropout operation,
extending battery life in portable systems.
SOT-23-5L

Pin configuration (Top view)
The switching frequency is internally set at 1MHz,
allowing the use of tiny surface mount inductor and
input/output capacitors.
The WD1039EB is available in SOT-23-5L package.
Standard product is Pb-free and Halogen -free.
