Features & Applications
An additional benefit of this proprietary architecture is very low output ripple voltage throughout the entire load range with the use of small output capacitors. The tiny 1.6 mm x 1.6 mm Thin MLF ® package saves precious board space and requires only three external components.The MIC23031 has a very low quiescent current of 21 µA and achieves as high as 88% efficiency at 1 mA. At higher loads, the MIC23031 provides a constant switching frequency around 4 MHz while achieving peak efficiencies up to 93%.
