Micrel MIC2193 400kHz SO-8 Synchronous Buck Control IC is a high efficiency PWM synchronous buck control IC from Micrel. It is housed in the space-saving SO-8 package. The 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 MIC2193 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 MIC2193 can implement all- ceramic capacitor solutions.
