2.7 V to 40V, 2A, Sync Buck-Boost
Simple Solutions to Your Power Conversion Challenges
®
The LTC 3115-1 is just one of our growing family of buck-boost converters, greatly simplifying designs where a fixed output
voltage is required even when the input can be above, below or equal to it. Applications with multiple input sources
typically face this challenge, necessitating a wide input range for this type of converter. The LTC3115-1’s 2.7V to 40V input
range easily manages these voltage levels and its 50µA quiescent current at no load is ideal for “always-on” systems. The
LTC3115-1 provides true output disconnect between the load and the input source in shutdown, and its low transition noise
minimizes interference with audio or RF circuitry.
