IS31LT3932 - High PF universal LED Driver

Key Features

  • IS31LT3932 is a universal LED driver, which can operate in fly-back, buck-boost and buck convertor. For isolation fly-back, it can achieve high PF, high current accuracy, ± 5 % load and line regulation and wide voltage input voltage range, without loop compensation. For buck convertor, it also can achieve high PF, high current accuracy, high efficiency, good load and line regulation and wide voltage input voltage range, without loop compensation. with very few components. IS31LT3932 has special.
