The LT3791 is a 4-switch synchronous buck-boost DC/DC converter that regulates both constant-current and constant-voltage at up to 98.5% efficiency with a single inductor. It can deliver hundreds of watts and features a 60V input and output rating, making it ideal for driving high power LED strings and charging high voltage batteries when both step-up and step-down conversion is needed. It can also be used as a constant-voltage buck-boost regulator with current limiting and monitoring for both input and output.
This document introduces the LT3791, a 4-switch synchronous buck-boost DC/DC converter capable of regulating constant-current and constant-voltage at efficiencies up to 98.5%. It features a wide input and output voltage range (60V rating), making it suitable for driving high-power LED strings and charging high-voltage batteries where both step-up and step-down conversion are required.
