Micrel MIC2196 400kHz SO-8 Boost Control IC is a high efficiency PWM boost control IC housed in a SO-8 package, optimized for low input voltage applications. 2.9V to 14V wide input voltage range, 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. 2 Ω output driver allows the MIC2196 to drive large external MOSFET, making it ideal for space-sensitive applications. Space-saving SO-8 package with low pin-count minimizes external components. 400kHz PWM operation allows a small inductor and small output capacitors to be used. 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. MIC2196 features a low current shutdown mode of 1µA and programmable undervoltage lockout.
