The MP2164 is a monolithic, step-down, switch-mode converter with built-in, internal power MOSFETs that can achieve 3A of continuous output current from a 2.5V to 5.5V input voltage range, with excellent load and line regulation. The output voltage can be regulated as low as 0.6V. The MP2164 is ideal for powering portable equipment that run on a single-cell Lithium-ion (Li+) battery.

Constant-on-time (COT) control scheme provides fast transient response, high light-­load efficiency, and easy loop stabilization. Full protection features include output over-voltage protection (OVP), cycle­-by­cycle current limiting, and thermal shutdown.

The MP2164 is available in a QFN-12 (2mmx2mm) package.
