Hot-selling and scarce MP2109DQ-LF-Z Dual 1.2MHz, 800mA Synchronous Step-Down Converter QFN10 spot stock

Product Descriptions

The MP2109 contains two independent 1.2MHz constant frequency, current mode, PWMstep-down  converters.  Each  converter integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. The MP2109 is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery. Each converter can supply 800mA of load current from a 2.5V to 6V input voltage.The output voltage can be regulated as low as 0.6V.The MP2109 can also run at 100%duty cycle for low dropout applications.
