dc1405a DC1405A LT3492EFE Demo Board | Boost/Buck-Boost Triple Output LED Driver, 8V ≤ VIN ≤ 40V, VLED = 54V @ 61mA (x3) Demonstration circuit 1405 is a Triple Boost or Buck/Boost LED Driver featuring the LT3492. The LT3492 is a triple output DC/DC converter designed to operate as current sources for driving LEDs using . Each of the three regulators on the demo board is independently operated. The board can be configured with?either boost (default) or buck-boost mode; buck mode is not supported. The current for each output is 61mA in either mode. The IC's input voltage range is 8V to 30V with 40V transient protection; however the LEDs input power source can be as high as 40V. ?The overvoltage protection (open LED detect) is set at 58V. For a typical application with a LED voltage of 3.6V, each boost circuit can drive around 15 LEDs. Applications with different input voltages and load combinations can be demonstrated on this circuit with some board modifications.? ? DC1405A
