  • The advantages of DCDC Constant Current Chip

    DC-DC constant current chips have been in high demand in recent times, owing to their numerous benefits. These embedded systems are well-equipped to handle a wide range of applications, such as automotive, IoT, medical devices, and telecommunications. In this article, we will discuss some of the significant advantages of DC-DC constant current chips.

  • ​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."
