MIC4742

The MIC4742 is a high efficiency dual PWM buck (step-down) regulator that provides dual 2A current output. The MIC4742 operates at 2MHz. A proprietary internal compensation technique allows a closed loop bandwidth of over 200kHz.

The low on-resistance internal P-channel MOSFET of the MIC4742 allows efficiencies over 92%, reduces external components count and eliminates the need for an expensive current sense resistor.

The MIC4742 operates from 2.9V to 5.5V input and the output can be adjusted down to 0.6V. The device can operate with a maximum duty cycle of 100% for use in low-dropout conditions.

The MIC4742 is available in ETSSOP-16 packages with a junction operating range from -40°C to +125°C.
