400kHz SO-8
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 boost, SEPIC (single ended primary inductive coupled), flyback topologies efficiently generate positive negative voltages. This evaluation board addresses topology where input voltage range used generate -5V. 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 topology. MIC2196 Evaluation Board Input/Output Voltages Load Current MIC2196 evaluation board designed input voltage output voltage evaluation board programmed different output voltage load current merely replacing components. Please consult factory your local Micrel Field Application Engineer implement this change. Quick-Start Guide Refer Figure following: Connect positive terminal from power supply post (J1) MIC2196 evaluation board. Connect terminal input power supply (J3). Connect digital voltmeter across VOUT (J2) (J4) measure output voltage. After turning input supply output voltage should read approximately -5V.
