15.17. MP2112
15.17.1. General Description
The MP2112 is a 1MHz constant frequency, current mode, PWM step-down converter.
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
powered by a single cell Lithium-Ion (Li+) battery. The MP2112 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. The MP2112 can also run at 100% duty cycle for low dropout applications.
The MP2112 is available in a space-saving 6-pin QFN package.
