60-V buck-boost LED driver offers 100 W

摘要

The LT3791 synchronous buck-boost dc/dc LED driver and voltage controller delivers 100-W power. It features 4.7 to 60-V input voltage that suits automotive, industrial and architectural lighting. The output voltage can be set from 0 to 60 V, enabling it to drive a wide range of LEDs in a single string. An internal four-switch buck-boost controller operates from input voltages above, below or equal to the output voltage.
