Product Summary
The MP2112DQ-LF-Z is a 1MHz constant frequency, current mode, PWM step-down converter. It integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. It is ideal for powering portable equipment that powered by a single cell Lithium-Ion (Li+) battery. The MP2112DQ-LF-Z can supply 1A of load current from a 2.5V to 6V input voltage. The output voltage can be regulated as low as 0.6V. It can also run at 100% duty cycle for low dropout applications. The MP2112DQ-LF-Z is available in space-saving 6-pin QFN and TSOT23-5 packages.
