MIC2194 is a high efficiency PWM buck control IC housed in the SO-8 package. Its 2.9V to 14V input voltage range allows it to efficiently step down voltages in 3.3V, 5V, and 12V systems as well as 1- or 2-cell Li-Ion battery powered applications. The flexible architecture of the MIC2194 allows for it to be configured as a buck or a buck-boost converter. The MIC2194 solution saves valuable board space. The device is housed in the space-saving SO-8 package, whose low pin-count minimizes external components. Its 400kHz PWM operation allows a small inductor and small output capacitors to be used. The MIC2194 can implement all-ceramic capacitor solutions. The MIC2194 drives a high-side P-Channel MOSFET. A low output driver impedance of 2ω allows the MIC2194 to drive large external MOSFETs to generate a wide range of output currents. The MIC2194 can achieve maximum duty cycles of 100%, which can be useful in low headroom applications. The MIC2194 is available in an 8-pin SOIC package with a junction temperature range of -40°C to +125°C.
