Fonctionnalités et applications
The MIC2172YN are complete 100 kHz SMPS current-mode controllers with internal 65 V 1.25 A power switches. The MIC2172 features external frequency synchronization or frequency adjustment.

Although primarily intended for voltage step-up applications, the floating switch architecture of the
MIC2172 makes it practical for step-down, inverting, and Cuk configurations as well as isolated topologies.

Feature:

  • 1.25 A, 65 V internal switch rating
  • 3 V to 40 V input voltage range
  • Current-mode operation
  • Internal cycle-by-cycle current limit
  • Thermal shutdown
  • Low external parts count
  • Operates in most switching topologies
  • 7 mA quiescent current (operating)
  • External frequency synchronization (MIC2172)
  • External frequency trim (MIC2172)
  • Fits most LT1172 sockets (see applications info)

Applications:

  • Laptop/palmtop computers
  • ToysHand-held instrumentsOff-line converter up to 50W (requires external power switch)
  • Predriver for higher power capability
  • Master/slave configurations (MIC2172)
