Introduction

AI Translation

The STI34061 is a high efficiency, current mode PWM step-down converter with PFM in light load. 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 battery. The output voltage can be regulated as low as 0.6V. The STI34061 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.
