    Category:

    Power Management ICs

    Manufacturer:

    Microchip

    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.

    Products Detail

    The MIC2171 is a current-mode switching regulator controller with a 2.5A, 65V internal switch. It operates from 3V to 40V input voltage range and draws only 7mA quiescent current, making it suitable for battery-operated supplies. The device features cycle-by-cycle current limiting, thermal shutdown, and operates at 100kHz (twice the frequency of LM2577). It is available in 5-pin TO-220 and TO-263 packages for industrial temperature range (-40°C to +85°C).

    Key Features
