说明
-
Typical Application for LT3478/LT3478-1 are 4.5A step-up DC-DC converters designed to drive LEDs with a constant current over a wide programmable range. Series connection of the LEDs provides identical LED currents for uniform brightness without the need for ballast resistors and expensive factory calibration
