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 few external components. IS31LT3932 has special power line sense and output voltage sense circuits, operates in primary feedback mode without Opto-coupler and achieve stable output current control without any loop compensation. IS31LT3932 has multiple protections to improve the system reliability, including LED open circuit, LED short circuit, UVLO, OVP, current sense resistor short, the primary over current limit and over temperature protections.
