Linear Technology’s LT3760 LED driver is an eight-channel device featuring a step-up dc/dc controller that drives up to a 45 V string of 100 mA LEDs per channel. Its internal 60 V, 1 MHz dc/dc boost mode controller operates as a constant current LED driver for up to 80 white LEDs. From a 12 V input, the unit can drive eight channels, each with up to 10 white 100 mA LEDs in series while delivering efficiencies exceeding 92%. Its multichannel capability makes it suitable for medium- and large-sized TFT-LCD backlighting applications; an input voltage range of 6-40 V enhances avionic and industrial display applications. LED current matching of ±2% ensures uniform display brightness.
