MIC2171WU More Semiconductors - ICs by Microchip Technology
2.5A 100kHz Switching Regulator
| Status: | Active |
|---|---|
| Series: | MIC2171 |
| RoHS: | Compliant |
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. The MIC2171 is available in a 5-pin TO-220 or TO-263 for -40°C to +85°C operation.
