Micrel MIC2186
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.| Part No. | MIC2186 |

GENERAL DESCRIPTION
Micrel’s 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 0.5µA and programmable undervoltage lockout. A manually selectable SKIP Mode allows high efficiencies in light load situations. The MIC2186 is available in 16 pin SOIC and QSOP package options with an operating range from –40°C to 125°C.FEATURES
