MP2164
2.5 - 5.5V, 3A, 2.3MHz, High Efficiency, Synchronous Step-Down Converter
with MODE Pin in Small 2x2mm QFN Package
DESCRIPTION
The MP2164 is a monolithic, step-down, switchmode converter with built-in, internal power MOSFETs that can achieve 3A of continuous output current from a 2.5V to 5.5V input voltage rangewith 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.
The constant-on-time (COT) control scheme provides fast transient response, high light-load efficiency, and easy loop stabilization.
Full protection features include output overvoltage protection (OVP), cycle-by-cycle current limiting, and thermal shutdown.
