General Description
Micrel’s MIC2185 is a high efficiency synchronous boost PWM control IC. With
its wide input voltage range of 2.9V to 14V, the MIC2185 can be used to
efficiently boost voltages in 1- or 2-cell Li Ion battery powered
applications, as well as fixed 3.3V and 5V systems. Its powerful 5Ω output
drivers allow the MIC2185 to supply large output currents with the selection
of the proper external MOSFETs.
With it’s fixed frequency PWM architecture, and easily synchronized drive, the
MIC2185 is ideal for noise-sensitive telecommunications applications. The
nominal 400kHz operating frequency of the MIC2185 can be divided by two,
allowing the device to be externally synchronized to frequencies below 400kHz.
The MIC2185 also features a low current shutdown mode and a programmable
undervoltage lockout. A skipped pulse mode of operation can be manually set to
achieve higher efficiencies at light load conditions.
The MIC2185 is available in a 16 pin SOIC package and 16 pin QSOP package with
an ambient temperature operating range from –40°C to 85°C.
