400kHz SO-8 Boost Control IC
Final Information
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 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.
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-sensitive telecommunications
applications.
MIC2196 features a low current shutdown mode of 1
μ
A and
programmable undervoltage lockout.
The MIC2196 is available in an 8-pin SOIC package with a
junction temperature range from –40
°
C to +125
°
C.
