Shenzhen SI Semiconductors Co., LTD. High Precision Non-Isolated Buck LED Driver General Description Product Specification SIC9552A/9553A/9554A/9555A/9556A The SIC9552A/9553A/9554A/9555A/9556A are high precision buck LED drivers. The chips are suitable for 85~265Vac universal input LED lighting applications. The SIC9552A/9553A/9554A/9555A/9556A integrate high-precision sampling and compensation circuit, the constant current of circuit can achieve accuracy under ± 3%. It can also achieve the adaptive demand between both output inductor current and output voltage, so as to achieve good linear regulation and load regulation. The SIC9552A/9553A/9554A/9555A/9556A integrate 500V power MOSFET.
