MPS MP2166 is a high-efficiency, dual-channel, synchronous step-down (buck) regulator designed for portable and battery-powered applications. It operates from a 2.7V to 6V input range, making it ideal for single-cell lithium-ion (Li+) battery systems. The device integrates two independent PWM controllers with internal compensation, enabling flexible 2A/2A or 3A/1A current configurations while maintaining ultra-low 60µA quiescent current for extended battery life.
