High Precision Non-Isolated Buck LED Driver
General Description
产品规格书 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 pensation 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...
