KP201 is a high performance current mode PWM controller for offline flyback converter applications. The IC supports DCM and CCM operation mode.

As a core component focusing on electronic control scenarios, KP86201's core advantages are reflected in control accuracy and operation stability. Adaptation compatibility and energy efficiency optimization are its key characteristics, which can not only meet the precise regulation needs under complex working conditions, but also provide solid support for the efficient operation of equipment. In electric The sub-control field shows a practical value that cannot be ignored.

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."

We provide diversified integrated chip solutions such as AC-DC, DC-DC, LDO and current limiting switch for smart meter applications to meet the high reliability and high performance requirements of meter applications.
