Product Details

Demonstration Circuit 1482 is a fully integrated, multitopology LED driver with a 45V, 750mA power switch featuring the LT3519. The board is optimized to drive a 100mA LED string from a 6V to 30V input power supply using a boost topology.The DC1482 has overvoltage protection at just above 40V if the LEDs are open or not properly attached to the terminals on the PCB.

The high input voltage range, integrated low-side power switch and catch diode, integrated compensation, low voltage floating current sense amplifier, high PWM dimming ratio, overvoltage protection, shutdown control pin, analog LED current dimming control, and fixed 400kHz switching frequency make the LT3519 an extremely versatile and powerful LED driving IC.
