Monolithic Power Systems MP2127

Description

The MP2127 is a fully integrated, internally compensated 1.2MHz fixed frequency PWM step-down converter. It is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) Battery, with an input range from 2.7V to 6V. The MP2127 can provide up to 2A of load current with output voltage as low as 0.8V. It can also operate at 100% duty cycle for low dropout applications. With peak current mode control and internal compensation, the MP2127 is stable with ceramic capacitors andsmall inductors. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown.MP2127 is available in the small 6-pin 3mmx3mm QFN package.
