The KP2591(A) is a resonant switching power controller based on half-bridge LLC resonant converter, which integrates half-bridge driver with 50% duty cycle, and the maximum operating frequency is up to 350kHz.

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.

The demo board is designed to demonstrate a highperformance 50WLED filament lamp solution with a full input voltage range. The demonstration board is realized through a highly integrated high-frequency direct drive gallium nitride boost boost PFC constant current controller KP1352, with 650V power GaN FET.

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.

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."
