Overview
The MIC4742 is a high efficiency dual PWM buck (step-down) regulator that provides up to 2A of output current for each channel. The MIC4742 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 MIC4742 allows efficiencies up to 92%, reduces external component count and eliminates the need for an expensive external current sense resistor. The MIC4742 operates from a 2.9V to 5.5V input and its output is adjustable down to 0.6V. The devices can operate with a maximum duty cycle of 100% for use in low-dropout applications.
