MIC4742 Datasheet (Micrel Semiconductor) - 2MHz Dual 2A Integrated Switch Buck Regulator

MIC4742, 2MHz Dual 2A Integrated Switch Buck Regulator

The Micrel 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.
