In March 12, 2012, Linear Technology launched the LT3791, a synchronous buck boost DC-DC LED driver and voltage controller, which can deliver over 100W of LED power.
Features and USP: Its 4.7 V to 60 V input voltage range makes it ideal for a wide variety of applications, including automotive, industrial and architectural lighting. Similarly, its output voltage can be set from 0 V to 60 V, enabling the LT3791 to drive a wide range of LEDs in a single string. Its internal 4-switch buck boost controller operates from input voltages above, below or equal to the output voltage, and is ideal for automotive applications, where the input voltage can vary dramatically during stop or start, cold crank and load dump scenarios. The LT3791’s unique design utilises three control loops to monitor input current, LED current and output voltage to deliver optimal performance and reliability.
