Produktöversikt

The LTC3110IUF#PBF is a bidirectional buck-boost DC to DC regulator with capacitor charger and balancer in 24 pin QFN package. Its wide 0.1V to 5.5V capacitor/battery voltage and 1.8V to 5.25V system backup voltage ranges make it well suited to wide variety of backup applications using super capacitors or batteries. A proprietary low noise switching algorithm optimizes efficiency with capacitor/battery voltages that are above, below or equal to system output voltage. The LTC3110 can autonomously perform transition from charge to backup mode or switch modes based on an external command. Pin selectable burst mode operation reduces standby current and improves light load efficiency which combined with 1µA shutdown current make the LTC3110 ideally suited for backup applications. The device also includes voltage supervisors for direction control and end of charge, general purpose comparator with open collector output for interfacing with microcontroller.
  • VSYS operating range from 1.71V to 5.25V

  • ±1% backup voltage accuracy
  • Automatic backup capacitor balancing
  • Fixed 1.2MHz switching frequency
  • 40µA quiescent current in burst mode operation
  • Built-in programmable multipurpose comparator with open collector output
  • Open collector outputs to indicate direction of operation and end of charge
  • Operating junction temperature range from -40°C to 125°C
