MIC4723
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.
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® package with a junction operating range from -40°C to +125°C.
