The TMI31601F is a constant switching frequency 1.5MHz, peak current mode step-down converter with force PWM operation mode. The devices integrate a main PMOSFET 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. This device offers two operation modes, Force PWM control Mode, which allows a high efficiency over the wider range of the load. TMI31601F adopts small size DFN1.6x1.6-6 package.
