GENERAL DESCRIPTION
The TMI3108 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 TMI3108 can also run at 100% duty cycle for low dropout operation, extending battery life in portable system....
