The LTC3115-1 is a high voltage monolithic synchronous buck-boost DC/DC converter from Analog Devices. Its wide 2.7V to 40V input and output voltage ranges make it well suited to a variety of automotive and industrial applications.
A proprietary low noise switching algorithm optimizes efficiency with input voltages that are above, below, or even equal to the output voltage, ensuring 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 the 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, makes the LTC3115-1 ideally suited for battery-powered applications. Additional features include output disconnect in shutdown, short-circuit protection, and internal soft-start.
The LTC3115-1 is available in a thermally enhanced 16-lead 4mm × 5mm × 0.75mm DFN and a 20-lead TSSOP package. This specific part, the LTC3115EFE-1#TRPBF, is supplied in a 20-TSSOP-EP package suitable for surface mounting.
