China 12W-50W Buck LED Power 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.

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.

An AC-DC Constant Current Chip is an integrated circuit designed to provide a stable current output while converting alternating current (AC) input to direct current (DC). These are commonly used in LED drivers and low-power lighting systems.

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.
