Microchip | MIC2196YM

The MIC2196YM is a high efficiency PWM boost control IC housed in the SO-8 package. The MIC2196 is optimized for low input-voltage applications. With its wide input voltage range of 2.9 V to 14 V, the MIC2196 can be used to efficiently boost voltages in 3.3 V, 5 V, and 12 V systems, as well as 1- or 2-cell Li Ion battery powered applications. Its powerful 2 Ohm output driver allows the MIC2196 to drive large external MOSFETs.

The MIC2196 is ideal for space-sensitive applications. The device is housed in the space-saving SO-8 package, whose low pin-count minimizes external components. Its 400 kHz PWM operation allows a small inductor and small output capacitors to be used. The MIC2196 can implement all-ceramic capacitor solutions.
