60VIN 350W LED Driver VIN IVINP IVINN VOUT IVINMON ISMON FAULT PWM 3000:1 ing imm PWM D GND SENSE + SENSE – 20A Outputs for LEDs or Current Sources That Are Easy to Parallel ® The LT 3763 is a high power synchronous step-down controller delivering up to 20A of output current to drive big LEDs. It can also be used as a current source for charging supercapacitors or lead acid batteries. Capable of sensing both input and output current, the LT3763 ensures accurate current limiting and regulation, enabling ±1.5% voltage regulation accuracy and ±6% current regulation accuracy. The device’s input voltage range of 6V to 60V and output from 0V to 55V provide design flexibility. Its FBIN pin is ideal for applications that require a peak power tracking function such as solar panel chargers.
