Status: End of Life
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 one-cell 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 efficiences over 85% in a small board area.
The MIC2142 can be configured to efficiently power a variety of loads. It is capable of providing a few mA output for supplying low power bias voltages; it is also capable of providing the 80mA needed to drive four white LEDs.
The MIC2142 is available in a SOT23-5 package with an ambient operating temperature range from -40°C to +85°C
