TIDA-00748, 60W Synchronous Boost LED Driver Reference Design for Automotive Application

TIDA-00748, 60W Synchronous Boost LED Driver Reference Design for Automotive Application. TIDA-00748 is a 60W Synchronous Boost Design for automotive LED application utilizing the Synchronous Boost Converter LM5122-Q1. This design applies to automotive lighting for exterior lighting such as headlights and taillights and also interior LED lighting systems. The design accepts an input voltage of 8Vin to 15Vin and can drive multiple strings of 6 to 7 LEDs (16V to 24V) in series at 3A constant current. It is a low cost solution and provides under voltage as well as overvoltage protection. This solutions offers 97% efficiency compared to inefficient nonsynchronous Boost solutions
