Product Summary

The MIC2193YM 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 MIC2193YM 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 MIC2193YM can implement allceramic capacitor solutions. It drives a high-side P-channel MOSFET, eliminating the need for high-side boot-strap circuitry. This feature allows the it to achieve maximum duty cycles of 100%, which can be useful in low headroom applications. A low output driver impedance of 4Ω allows the MIC2193YM to drive large external MOSFETs to generate a wide range of output currents. The MIC2193YM is available in an 8 pin SOIC package with a junction temperature range of –40℃ to +125℃.
