LT3791 Datasheet 60v 4-switch Synchronous Buck-boost Led Driver Controller

Manufacturer: Linear Technology (now Analog Devices)

General 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.

The LT3791 has a wide 4.7V to 60V input and 0V to 60V output range along with seamless transitions between operating modes.
