MIC2145 High Efficiency 2.5W Boost Converter

The MIC2145 is a small size boost Switching Regulator that CAN provide over 2.5W of output power. The input voltage range is between 2.4V to 16V, making the device suitable for one-cell Li-Ion and 3- to 4-cell alkaline/NiCad/NiMH applica- tions. The output voltage of the MIC2145 CAN be adjusted up to 16V. The MIC2145 is well suited for portable, space-sensitive applications. Its typical 450kHz operation allows small sur- face mount external components to be used. The MIC2145 has a low quiescent current of 200, and a typical shutdown current of 0.5. The MIC2145 is capable of high efficiencies in a small board area. By Micrel Semiconductor
