Overview

MIC4722 3mm x 3mm 2.
7MHz 3A PWM Buck Regulator www.
datasheet4u.
com General Description The Micrel MIC4722 is a high efficiency PWM buck (stepdown) regulator that provides up to 3A of output current.
The MIC4722 operates at 2.
7MHz that makes it suitable for next generation XDSL modems requiring operating frequencies in excess of 2.
4MHz and has proprietary internal compensation that allows a closed loop bandwidth of over 200KHz.
The low on-resistance internal p-channel MOSFET of the MIC4722 allows efficiencies over 92%, reduces external components count and eliminates the need for an expensive current sense resistor.
The MIC4722 operates from 2.
7V to 5.
5V input and the output can be adjusted...
