Introduction

AI Translation

The LTC3115-2 is a high voltage monolithic synchronous buck-boost DC/DC converter optimized for applications subject to fast (<1ms) input voltage transients. With its wide 2.7V 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 the LTC3115-2 ideally suited for battery-powered applications. Additional features include output disconnect in shutdown, short-circuit protection and internal soft-start. The LTC3115-2 is available in thermally enhanced 16-lead 4mm × 5mm × 0.75mm DFN and 20‑lead TSSOP packages.
