MIC2186 Overview
Micrel’s MIC2186 is a high efficiency boost PWM control IC. With its wide input voltage range of 2.9V to 14V, the MIC2186 can be used to efficiently boost voltages in 1- or 2-cell Li Ion battery powered applications, as well as to boost voltages in fixed 3.3V, 5V, or 12V systems. Its powerful 1.6Ω output driver allows the MIC2186 to supply large output currents with the selection of proper external MOSFETs.
