MIC4744 Datasheet (Micrel Semiconductor) - 4 MHz Dual 2A Integrated Switch Buck Regulator

MIC4744, 4 MHz Dual 2A Integrated Switch Buck Regulator

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.
