MIC2193 Micrel MIC2193 400kHz SO-8 Synchronous Buck Control IC General Description Micrel’s MIC2193 is a high efficiency, PWM synchronous 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 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 allceramic capacitor solutions. The MIC2193 drives a high-side P-channel MOSFET, eliminating the need for high-side boot-strap circuitry.
