www.DataSheet4U.com MIC4720 3mm x 3mm 2.0MHz 2A Integrated Switch Buck Regulator General Description The Micrel MIC4720 is a high efficiency PWM buck (stepdown) regulator that provides up to 2A of output current. The MIC4720 operates at 2.0MHz and has proprietary internal compensation that allows a closed loop bandwidth of over 200KHz. The low on-resistance internal p-channel MOSFET of the MIC4720 allows efficiencies over 92%, reduces external components count and eliminates the need for an expensive current sense resistor. The MIC4720 operates from 2.7V to 5.5V input and the output can be adjusted down to 1V. The devices can operate with a maximum duty cycle of 100% for use in lowdropout conditions.
