600mA, 1.5MHz Synchronous Step-Down Converter
SD8906A
The SD8906A is a constant frequency, current mode PWM step-down converter.The
device integrates a main switch and a synchronous rectifier for high efficiency
without an external Schottky diode. It is ideal for powering portable equipment that
runs from a single cell Lithium-Ion (Li+) battery. The output voltage can be regulated
as low as 0.6V. The SD8906A can also run at 100% duty cycle for low dropout operation,
extending battery life in portable system. This device offers two operation modes,
PWM control and PFM Mode switching control, which allows a high efficiency over
the wider range of the load.
The SD8906A is offered in a low profile (1mm) 5-pin, thin SOT package, and is available in
an adjustable version and fixed output voltage of 1.2V,1.5V, 1.8V,2.5V and 3.3V.
