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 all-ceramic capacitor solutions.

The MIC2193 drives a high-side P-Channel MOSFET, eliminating the need for high-side boot-strap circuitry. This feature allows the MIC2193 to achieve maximum duty cycles of 100%, which can be useful in low headroom applications. A low output driver impedance of 4ω allows the MIC2193 to drive large external MOSFETs to generate a wide range of output currents.

The MIC2193 is available in an 8-pin SOIC package with a junction temperature range of -40°C to +125°C.
