DC3008A Demo Circuit for LT8386

Analog Devices DC3008A Demo Circuit for LT8386 is a 60V 3A Silent Switcher synchronous step-up LED driver featuring the LT8386. It drives a single string of LEDs at 500mA up to 45V when VIN is between 4V and 40V. It runs down to VIN with reduced ILED and can withstand VIN as high as 50V but has overvoltage lockout (OVLO) set for 45V for this application. DC3008A runs at 340kHz switching frequency. Spread spectrum frequency modulation (SSFM) can be turned on with a simple jumper, reducing EMI. Analog Devices DC3008A comes with low EMI features, including optimized layout, SSFM, and input EMI filter.
