MIC2193 - 400kHz SO-8 Synchronous Buck Control IC
Docket ↓MIC2193 Micrel MIC2193
400kHz SO-8 Synchronous Buck Control IC General Description Features Micrel’s MIC2193 is a high efficiency, PWM synchronous
buck control IC housed in the SO-8 package. Its 2.9V to 14V
input voltage range allows it to efficiently step down voltages
in 3.3V, 5V, and 12V 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 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 4Ω allows the MIC2193 to
drive large external MOSFETs to generate a wide range of
output currents.
The MIC2193 is available in an 8 pin SOIC package with a
junction temperature range of –40°C to +125°C. 2.9V to 14V input voltage range

MIC2196 - 400kHz SO-8 Boost Control IC
Docket ↓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 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
