The STI3408B 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 STI3408B 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.
