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. 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 4 allows the MIC2193 to drive large external MOSFETs to generate a wide range of output currents.
