MP2109DQ

MP2109 Dual 1.2MHz, 800mA Synchronous Step-Down Converter The Future of Analog IC Technology DESCRIPTION The MP2109 contains two independent 1.2MHz constant frequency, current mode, PWM step-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.
