MIC2186 Micrel, Inc. MIC2186
Low Voltage PWM Control IC General Description Features 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
0.5ВµA 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. Input voltage range: 2.9V to 14V
