MP2122A 6V, 2A, Low Quiescent Current, Dual, Synchronous Buck Regulator DESCRIPTION The MP2122A is an internally compensated, 1MHz, fixed-frequency, dual, PWM, synchronous, step-down regulator with advanced light-load mode. The MP2122A operates from a 2.7V to 6V input, generates an output voltage as low as 0.608V, and has a 45µA quiescent current, making it ideal for powering portable equipment that run on a single-cell lithium-ion (Li+) battery. The MP2122A integrates dual, 80mΩ, high-side switches and 35mΩ, synchronous rectifiers for high efficiency without an external Schottky diode. Peak-current mode control and internal compensation limits the minimum number of readily available external components.
