China Dual-Tube PFC Chip Manufacturer, Supplier, Factory

This DEMO Board provides 100W CrM Boost PFC Solution. The controller KP2801A enables to drive without auxiliary winding ZCD sensing by Novel Drain sensing tech...

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.

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

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."

Cokintech is a manufacturer specializing in various DC-DC Constant Voltage Chips. Today, we'll share the advantages of this type of constant voltage chip.
