DESCRIPTION

The LT®3791 is a synchronous 4-switch buck-boost LED driver and voltage regulator controller. The controller operates from input voltages above, below, or equal to the output voltage. A ground reference voltage FB pin serves as the input for several LED protection features and also makes it possible for the converter to operate as a constant-voltage source. Fault protection is provided to survive and report an open or shorted LED condition.
