توضیحات
SIC9555A يک ايسي درايور اليدي تک کاناله با ولتاژ عملياتي 85 تا 265 VAC و نياز به قطعات و ساختار ساده و ارزان قيمت بخاطر ماسفت 500 ولت داخلي براي درايو اليدي با اعمال محدوديت جريان ، محافظ اتصال کوتاه دارد.
از کاربرد هاي اين ايسي ميتوان به لامپ هاي اليدي خيابان ، اليدي هاي حبابي ، تيوب هاي T5/T8 و.... هرجا که نياز به درايور کوچک و کم هزينه اليدي باشد اشاره کرد.
Description
The SIC9552A/9553A/9554A/9555A/9556A are high precision buck LED drivers. The chips are suitable for85~265Vac universal input LED lighting applications.The SIC9552A/9553A/9554A/9555A/9556A integrate high-precision sampling and compensation circuit, theconstant current of circuit can achieve accuracy under ± 3%. It can also achieve the adaptive demand betweenboth 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 structureof the system can be benefit from its precise and stable adaptive technology. It is able to work without secondaryfeedback circuitry or compensation circuitry. The SIC9552A/9553A/9554A/9555A/9556A can achieve precisionconstant current control under a small number of peripheral devices and loosen parameter conditions. Suchfeatures can greatly save both cost and size of the system. At the same time, it can ensure the consistency ofparameters when making mass production of LED lighting devices.The SIC9552A/9553A/9554A/9555A/9556A have extensive protection features, including LED open protection,LED short protection, current sampling resistor short protection, VDD under-voltage protection, over-temperatureprotection.
