General Description

The Micrel MIC4721 is a high efficiency PWM buck (stepdown) regulators that provides up to 1.5A of output current.

The MIC4721 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 MIC4721 allows efficiencies up to 94%, reduces external components count and eliminates the need for an expensive current sense resistor.
