General 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.

Key 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 (o.
