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 500V power MOSFET. The simple peripheral structure of the system can be benefit from its precise and stable adaptive technology. It is able to work without secondary feedback circuitry or pensation circuitry. The SIC9552A/9553A/9554A/9555A/9556A can achieve precision constant current control under a small number of peripheral devices and loosen parameter conditions. Such features can greatly save both...
