In many cases, a step-up and step-down topology is needed due to the voltage variation of both the LED string and the input source. In this case, a 4-switch synchronous buck-boost controller is the best solution for its efficiency and small circuit size. Linear Technology’s LT®3791 is a buck-boost controller IC that drives LED strings from an input voltage up to 60 V to an output voltage up to 60 V.
