High Efficiency Switch Mode 3.3V 5A Step-Down Converter

This switch mode step-down converter has very good efficiency, up to 94% can be obtained. This switch mode regulator uses LTC1266-3.3 controller with external N-Channel power mosfet, and need only a 5uH inductor because it uses high frequency switching. Here is the schematic diagram of this switch mode step down converter circuit: To optimize efficiency, the LTC1266¬† automatically switches between […]
