MIC4723  
3A 2MHz Integrated Switch  
Buck Regulator  
General Description  
Features  
The Micrel MIC4723 is a high efficiency PWM buck (step-  
down) regulator that provides up to 3A of output current.  
The MIC4723 operates at 2.0MHz and has proprietary  
internal compensation that allows a closed loop bandwidth  
of over 200KHz.  
2.7/3.0V to 5.5V 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  
Ultra-small external components  
Stable with a 1µH inductor and a 4.7µF output  
capacitor  
Fully integrated 3A MOSFET switch  
Micropower shutdown  
Thermal shutdown and current limit protection  
Pb-free 12-pin 3mm x 3mm MLF® package  
Pb-free 10-pin ePAD MSOP package  
–40°C to +125°C junction temperature range  
The low on-resistance internal p-channel MOSFET of the  
MIC4723 allows efficiencies over 92%, reduces external  
components count and eliminates the need for an  
expensive current sense resistor.  
The MIC4723 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 low-  
dropout conditions.  
The MIC4723 is available in the exposed pad 12-pin  
3mm x 3mm MLF® and 10-pin ePAD MSOP packages with  
a junction operating range from –40°C to +125°C.
