400kHz SO-8 Boost Control
Introduction
MIC2196 high efficiency boost control housed SO-8 package. MIC2196 optimized input voltage applications. With wide input voltage range 2.9V 14V, MIC2196 used efficiently boost voltages 3.3V, systems. MIC2196 ideal space sensitive applications. device housed space saving SO-8 package, whose pin-count minimizes external components. fixed 400kHz operation allows small inductor small output capacitors ideal noise-sensitive telecommunication applications. Efficiencies over achievable over wide range load conditions. MIC2196 Evaluation Board Input/Output Voltages Load Current MIC2196 evaluation board designed following input/output voltages:
