MIC2171 Datasheet (Micrel Semiconductor) - 100kHz 2.5A Switching Regulator

MIC2171, 100kHz 2.5A Switching Regulator

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
