Product Overview

The LTC3115EFE-2#PBF is a 40V 2A monolithic synchronous buck-boost DC/DC Converter optimized for applications subject to fast input voltage transients. With its wide 2.7 to 40V input and output voltage ranges, the LTC3115-2 is well suited for use in a wide variety of automotive and industrial power supplies. A proprietary low noise switching algorithm optimizes efficiency with input voltages that are above, below or even equal to the output voltage and ensures seamless transitions between operational modes. Programmable frequency PWM mode operation provides low noise, high efficiency operation and the ability to synchronize switching to an external clock. Switching frequencies up to 2MHz are supported to allow use of small value inductors for miniaturization of the application circuit. Pin selectable Burst Mode® operation reduces standby current and improves light load efficiency which, combined with a 3µA shutdown current, make it ideally suited for battery-powered applications.
  • 0.8A Output current for VIN >= 3.6V, VOUT = 5V
  • 2A Output current in step-down operation for VIN >=6V
  • 100kHz to 2MHz Programmable frequency
  • Synchronizable up to 2MHz with an external clock
  • Up to 95% efficiency
  • 30µA No-load quiescent current in Burst Mode® operation
  • Ultralow noise buck-boost PWM
  • Internal soft-start
  • 3µA Supply current in shutdown
  • Programmable input under-voltage lockout
