MP2149GJ Description
The MP2149 is an internally-pensated, 1MHz fixed-frequency, dual PWM, synchronous, step-down regulator. The MP2149 operates from a 2.7V-to-6V input, generates an output voltage as low as 0.608V, and has a 45µA quiescent current that makes it ideal for powering portable equipment that runs on a single cell lithium-ion (Li+) battery. The MP2149 integrates dual 100mΩ high-side switches and 40mΩ synchronous rectifiers...
