Product Details

Demonstration circuit 1319B-A/1319B-B is a high voltage and high current LED driver controller. The VIN pin input voltage is as high as 100V, and the LED output voltage is also as high as 100V. The demonstration circuit is assembled as a boost topology from 8V to 80V input and up to 80V LED output at 0.5A with an open-LED status pin (DC1319B-A) or a sync input pin (DC1319B-B). DC1319B features PWM dimming, analog dimming, shutdown, and open-LED overvoltage protection.

Product Details

Demonstration circuit 1319B is a high voltage and high current LED driver controller feature the LT3756-1 (DC1319B-B) or the LT3756-2 (DC1319B-A). The device's VIN pin input voltage and LED output voltage can be as high as 100V; however, the demo board's open-LED overvoltage protection limits the input voltage to 80V and limits the output to approximately 92V if the LED string is opened.The demonstration circuit is assembled as a boost topology from 8V to 80V input and up to 80V LED output at 0.5A and features an open-LED status pin (DC1319B-A) or a sync input pin (DC1319B-B). DC1319B also features PWM dimming, analog dimming, shutdown, and open-LED overvoltage protection.
