MIC2203 Datasheet (Micrel Semiconductor) - High Efficiency 1MHz Synchronous Buck Regulator

MIC2203, High Efficiency 1MHz Synchronous Buck Regulator

The MIC2203 is an ultra-high efficiency, high frequency synchronous buck (step-down) switching regulator.

Efficiencies above 90% are easily obtainable for a wide variety of applications.

In addition, the MIC2203 has a logic compatible-enable function, which provides near “zero” OFF mode quiescent cu

MIC2203 Features

* internal power MOSFETs that can supply up to 300mA output current. It can operate with a maximum duty cycle of 100% for low-dropout conditions and regulate output voltages down to 0.5V. The MIC2203 is a constant frequency pulse width modulation (PWM) buck converter that maintains high efficiency eve
