รายละเอียดสินค้า / Product Details

The MIC2171 is a complete 100kHz SMPS current-mode controller with an internal 65V 2.5A power switch. Although primarily intended for voltage step-up applications, the floating switch architecture of the MIC2171 makes it practical for step-down, inverting, and Cuk configurations as well as isolated topologies. Operating from 3V to 40V, the MIC2171 draws only 7mA of quiescent current, making it attractive for battery operated supplies.
