16 channel constant current drive chip for LED display using high speed four component time technology

Due to the application of LED display is more and more widely, especially the LED luminous efficiency continues to improve, and to reduce the cost and reduce the overall power consumption demand, line scanning LED display scheme has been used in a large amount and growth. But LED display the original line scanning solution has low refresh rate, great loss, low gray serious power supply noise and EMI, although riyuecheng technology and other suppliers are offering can improve the refresh rate and improve other solutions, but the low gray, such schemes are a common disadvantage that the control system is complicated, high cost, high power supply noise. For IIC2011 in Shenzhen exhibition, riyuecheng technology for line scan display applications launched with a high refresh rate, high intensity, low system power consumption, low noise and power supply EMI, compatible with innovative universal control system of 16 channel constant current LED driver chip SUM2016/SUM2022. SUM2016 using riyuecheng technology patented StabilityDriveTM technology and high-speed four component technology, in the realization of less than 40ns fast open at the same time, the excellent line output current response, outstanding low ash performance, multi line scan to maintain high refresh rate, the overall power consumption can be reduced by more than 10%, significantly reduce the EMI support the existing universal control system and other advantages. The main features of SUM2016/SUM2022: constant current output range: 0.6mA ~ 45mA low output voltage constant current output constant current (mA) output voltage (V) = 30.45 ~ 5 = 300.55 ~ 5 = 450.6 ~ 5LED voltage SUM2016:9VSUM2022:18V

Product status: SUM2016 and SUM2022 is available now, with SSOP24-1.0 and SSOP24-0.635 package. Products through the China CEPREI (Jiangsu) through laboratory examination and testing. Riyuecheng technology is a national high-tech enterprises, outstanding enterprises in Jiangsu Province, through the ISO9001 certification, IC design enterprise for the Ministry of industry and information technology. The company has "Suzhou semiconductor lighting integrated circuit engineering and Research Center, VLSI Institute of Zhejiang University jointly set up a" power analog integrated circuit engineering center, dozens of independent intellectual property rights. Long term for the world's top 500 Japanese companies to provide ODM services. Production and sales of LED driver chip more than and 10 models.
