MIC2196
400kHz SO-8 Boost Control IC
General Description
Features
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 2 ? 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.
