Features & Applications

The MIC2171WU is a complete 100 kHz SMPS current-mode controller with an internal 65 V 2.5 A 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 3 V to 40 V, the MIC2171 draws only 7 mA of quiescent current, making it attractive for battery operated supplies.

Features:

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

Applications:

  • Laptop/palmtop computersBattery operated equipment
  • Hand-held instruments
  • Off-line converter up to 50 W
  • (requires external power switch)
  • Predriver for higher power capability
