Product Overview

The LTC3111EMSE#PBF is a fixed frequency synchronous buck-boost DC-to-DC Converter with an extended input and output range. The unique 4-switch, single inductor architecture provides low noise and seamless operation from input voltages above, below or equal to the output voltage. With an input and output range of 2.5 to 15V, the LTC3111 is well suited for a wide variety of single or multiple-cell batteries, back-up capacitor or wall adapter source applications. Low RDS(ON) internal N-channel MOSFET switches and selectable PWM or Burst Mode® operation produce high efficiency over a wide range of operating conditions. An accurate RUN pin allows the user to program the turn-ON threshold voltage of the converter. Other features includes short-circuit protection, internal soft-start and thermal shutdown.
  • Single inductor
  • Output disconnect in shutdown
  • Internal soft-start
  • Up to 95% efficiency
  • Synchronizable between 600kHz and 1.5MHz
  • 49µA No-load quiescent current in Burst Mode® operation
  • <1µA Shutdown current
