This DEMO board is a high performance nonisolated 600W constant current LED driver which is controlled by KP1469.Besides the multi-protection function (OVP, SCP, OTP), this demo also has very good efficiency, load regulation, low standby power loss and wide dimming range.

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."
