Microchip | MIC2193YM

The MIC2193YM is a high efficiency, PWM synchronous buck control IC housed in the SO-8 package. Its 2.9 V to 14 V input voltage range allows it to efficiently step down voltages in 3.3 V, 5 V, and 12 V 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.
