MIC4722 Overview
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 pensation that allows a closed loop bandwidth of over 200KHz. The low on-resistance internal p-channel MOSFET of the MIC4722 allows...
