Overview
MIC2196 400kHz SO-8 Boost Control IC General Description Micrel’s MIC2196 is a high efficiency PWM boost control IC housed in a SO-8 package.
The MIC2196 is optimized for low input voltage applications.
With its wide input voltage range of 2.
9V to 14V, the MIC2196 can be used to efficiently boost voltages in 3.
3V, 5V, and 12V systems, as well as 1- or 2-cell Li Ion battery powered applications.
Its powerful 2Ω 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 400kHz PWM operation allows a small inductor and small output capacitors to be used.
The MIC2196 can implement all ceramic capacitor solutions.
Efficiencies over 90% are achievable over a wide range of load conditions with the MIC2196’s PWM boost control scheme.
Its fixed frequency PWM architecture also makes the MIC2196 is ideal for noise-sensit...
