Description

General part information

MP2149 Series

The MP2149 is an internally-compensated, 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 100m? high-side switches and 40m? 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. Fault-condition protections include cycle-by-cycle current limiting and thermal shutdown. The MP2149 is available in an 8-pin TSOT23-8 package.Dual 1A-Output Current >93% Peak Efficiency >80% Light-Load Efficiency Wide 2.7V-to-6V Operating Input Range 100m? and 40m?
