MIC4724 Data Sheet Docket ↓MIC4724 3A 2MHz Integrated Switch Buck Regulator with 6Vmax Input General Description Features The Micrel MIC4724 is a high efficiency PWM buck (stepdown) regulator that provides up to 3A of output current. The MIC4724 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 MIC4724 allows efficiencies over 92%, reduces external components count and eliminates the need for an expensive current sense resistor. The MIC4724 operates from 3.0V to 6.0V 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. The MIC4724 is available in 10-pin ePAD MSOP package with a junction operating range from –40В°C to +125В°C. Data sheets and support documentation can be found on Micrel’s web site at: www.micrel.com. 3.0 to 6.0V supply voltage 2.0MHz PWM mode Output current to 3A Up to 94% efficiency 100% maximum duty cycle Adjustable output voltage option down to 1V Ultra-fast transient response ...
