MIC2196

Micrel's MIC2196 is a high efficiency PWM boost control IC housed in the 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-sensitive telecommunications applications.

MIC2196 features a low current shutdown mode of 1µA 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.
