  • The characteristics of ACDC Constant Current Chip

    An AC-DC Constant Current Chip is an integrated circuit designed to provide a stable current output while converting alternating current (AC) input to direct current (DC). These are commonly used in LED drivers and low-power lighting systems.

  • ​How Does Integrated EMI Filter in ACDC Constant Current Chip Simplify Power Supply Design?

    This technological leap demonstrates its advantages in wide-voltage scenarios. When the input voltage jumps from 90V to 264V, Huqin's ACDC chip can dynamically adjust the internal electromagnetic structure to keep the noise attenuation rate consistently above 42dB. However, when the voltage of a certain competing product's DCDC solution undergoes a sudden change, the filtering effect will decline by 15dB. This is like teaching the chip "metamorphosis". Test engineer Xiao Zhang pointed at the spectrum analyzer and said, "Our chip can reconstruct the electromagnetic topology in real time based on the interference frequency. This kind of intelligent response is something that discrete solutions can never catch up with."
