MIC2185BM-TR is a high efficiency synchronous boost PWM control IC. With its wide input voltage range of 2.9V to 14V, the MIC2185BM-TR 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 5 Ohm output drivers allow the MIC2185BM-TR 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 MIC2185BM-TR is ideal for noise-sensitive telecommunications applications. The nominal 400kHz operating frequency of the MIC2185BM-TR can be divided by two, allowing the device to be externally synchronized to frequencies below 400kHz.
The MIC2185BM-TR 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 MIC2185BM-TR 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.
