MIC4744
The Micrel MIC4744 is a high efficiency dual PWM buck (step-down) regulator that provides dual 2A current output. The MIC4744 operates at 4MHz. A proprietary internal compensation technique allows a closed loop bandwidth of over 200kHz.
The low on-resistance internal P-Channel MOSFET of the MIC4744 allows efficiencies over 90%, reduces external components count and eliminates the need for an expensive current sense resistor.
The MIC4744 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 MIC4744 is available in the exposed pad 16-pin 3mm x 3mm MLF® and ETSSOP-16 packages with junction operating temperature ranging from –40°C to +125°C.
