MIC2171
Description
The MIC2171 is a plete 100k Hz 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 7m A of quiescent current, making it attractive for battery operated supplies.
The MIC2171 is available in a 5-pin TO-220 or TO-263 for
- 40°C to +85°C operation.
