Product Overview

The LTC3118HFE#PBF is a dual-input wide voltage range synchronous buck-boost DC-to-DC Converter with an intelligent, integrated and low loss PowerPath™ control. The unique power switch architecture provides efficient operation from either input source to a programmable output voltage above, below or equal to the input. Voltage capability of up to 18V provides flexibility and voltage margin for a wide variety of applications and power sources. It uses a low noise, current-mode architecture with a fixed 1.2MHz PWM mode frequency that minimizes the solution footprint. For high efficiency at light loads, automatic Burst Mode® operation can be selected consuming only 50µA of quiescent current in sleep. System level features include ideal diode or VIN priority modes, VIN and VOUT power good indicators, accurate RUN comparators to program independent UVLO thresholds and output disconnect in shutdown. Other features include 2µA shutdown current, short-circuit protection and soft-start.
  • Ideal diode or priority VIN select modes
  • Either VIN can be above, below or equal to VOUT
  • Current-mode control
  • All internal N-channel MOSFETs
  • Accurate, independent RUN pin thresholds
  • Up to 94% efficiency
  • VIN and VOUT power good indicators
