MIC2172/3172 100kHz 1.25A Switching Regulators General Description The MIC2172 and MIC3172 are plete 100kHz SMPS current-mode controllers with internal 65V 1.25A power switches. The MIC2172 Features external frequency synchronization or frequency adjustment, while the MIC3172 Features an enable/shutdown control input. Although primarily intended for voltage step-up applications, the floating switch architecture of the MIC2172/3172 makes it practical for step-down, inverting, and Cuk configurations as well as isolated topologies. Operating from 3V to 40V, the MIC2172/3172 draws only 7mA of quiescent current making it attractive for battery operated supplies. The MIC3172 is for...
