GENERAL DESCRIPTION
FEATURES
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 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 4 white LEDs. The MIC2142 is available in a SOT23-5 package with an ambient operating temperature range from –40°C to +85°C.
