The LTC3115EFE-1#PBF is a high voltage monolithic synchronous Buck-boost DC/DC Converter. Its wide 2.7 to 40V input and output voltage range. 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 valued 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 this ideally suited for battery-powered applications. Additional features include output disconnect in shutdown, short-circuit protection and internal soft-start.
