MIC2203 Evaluation Board
High Efficiency 1MHz Buck Converter
General Description
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 current for power critical battery applications.
The MIC2203 operates from 2.
3V to 5.
5V input and 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.
