M3406-ADJ 1.5MHz - 800mA - Synchronous - DC-DC Step-Down Converter IC - SOT-23-5

Datasheet

The M3406 is a constant frequency, current mode step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency without a 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 M3406 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.
