Description
General part information
MIC4721 Series
The MIC4721 is a high efficiency PWM buck (step-down) regulators that provides up to 1.5A of output current. The MIC4721 operates at 2MHz and has proprietary internal compensation that allows a closed loop bandwidth of over 200kHz.
The low on-resistance internal p-channel MOSFET of the MIC4721 allows efficiencies up to 94%, reduces external components count and eliminates the need for an expensive current sense resistor.
The MIC4721 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.
