Fonctionnalités et applications
The MIC3172YM TR are complete 100kHz SMPS current-mode controllers with internal 65 V 1.25A power switches. The MIC3172 features an enable/shutdown control input. Although primarily intended for voltage step-up applications, the floating switch architecture of the MIC3172 makes it practical for step-down. Operating from 3V to 40V, the MIC3172 draws only 7mA of quiescent current making it attractive for battery operated supplies.

The MIC3172 is for applications that require on/off control of the regulator. The MIC3172 is externally shutdown by applying a TTL low signal to EN (enable). When disabled, the MIC3172 draws only leakage current (typically less than 1µA).

Features:

  • 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 shutdownLow external parts count
  • Operates in most switching topologies
  • 7 mA quiescent current (operating)
  • < 1 µA quiescent current, shutdown mode
  • TTL shutdown compatibility
  • Fits most LT1172 sockets

Applications:

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