Overview

MIC2142 Micropower Boost Converter General Description Features The MIC2142 is a micropower boost switching regulator housed in a SOT23-5 package.
The input voltage range is between 2.
2V to 16V, making the device suitable for onecell Li Ion and 3 to 4-cell alkaline/NiCad/NiMH applications.
The output voltage of the MIC2142 can be adjusted up to 22V.
The MIC2142 is well suited for portable, space-sensitive applications.
It features a low quiescent current of 85µA, and a typical shutdown current of 0.
1µA.
It’s 330kHz operation allows small surface mount external components to be used.
The MIC2142 is capable of efficiencies over 85% in a small board area.
The MIC2142 can be conﬁgured to effi...
