WD1015
WD1015
1.5MHz, 1.2A, Step-down DC-DC Converter
Http//:www.sh-willsemi.com
Descriptions
The WD1015 is a high efficiency, synchronous step
down DC-DC converter optimized for battery powered
portable applications. It supports up to 1.2A 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 WD1015 operates at 1.5MHz 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
The switching frequency is internally set at 1.5MHz,
allowing the use of tiny surface mount inductor and
input/output capacitors. Low output voltage is easily
supported with the 0.6V feedback reference voltage.
Pin configuration (Top view)
The WD1015 is available in SOT-23-5L package.
Standard product is Pb-free and Halogen-free.
