MIC2186 Micrel, Inc. MIC2186 Low Voltage PWM Control IC General Description 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. The MIC2186 can be configured to operate at 100kHz, 200kHz, or 400kHz. With it’s fixed frequency PWM architecture, and easily synchronized drive, the MIC2186 is ideal for noise-sensitive telecommunications applications. MIC2186 also features a low current shutdown mode of 0.
