GENERAL DESCRIPTION
- 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.
