MIC2171WU by Microchip Technology

2.5A 100kHz Switching Regulator
Features
2.5A, 65V internal switch rating
3V to 40V input voltage range
Current-mode operation, 2.5A peak
Internal cycle-by-cycle current limit
Thermal shutdown
Twice the frequency of the LM2577
Low external parts count
Operates in most switching topologies
7mA quiescent current (operating)
Fits LT1171/LM2577 TO-220 and TO-263 sockets
Description

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.
