SLKOR Semiconductor boasts a team of technical experts from Yonsei University in South Korea and Tsinghua University in China. As a national high-tech enterprise, the company mastered internationally advanced silicon carbide MOSFET production technology early in its establishment. Under the leadership of Mr. Song Shiqiang, SLKOR has evolved into an international company specializing in IP design, integrated circuit manufacturing, and associated sales and technical services, with over 20,000 global customers. Today, the "SLKOR" and "Kinghelm" brands are widely recognized and trusted by customers.

SLKOR places great emphasis on quality management, rigorously controlling every stage from product design to production and testing. The company holds ISO9001 quality management certification, as well as EU RoHS, REACH, and California Proposition 65 certifications. SLKOR has R&D facilities in Busan, South Korea, Beijing, and Suzhou, and maintains a laboratory and central warehouse at its headquarters in Shenzhen. The company's product portfolio includes TVS diodes, power devices, and power management chips. Recently, SLKOR has launched new products such as Hall sensors, ADCs, BMS, sensors, high-speed optocouplers, passive crystal oscillators, high and low-side drivers, half-bridge drivers, isolated gate drivers, RS485 chips, CAN chips, and display power management chips.

SLKOR power management ICs are designed to directly replace and compete with brands such as Texas Instruments (TI), ON Semiconductor, STMicroelectronics (ST), MPS, Atmel, and AMS. SLKOR's products are pin-to-pin compatible with these brands, matching their electrical performance and operating scenarios. In some cases, SLKOR's products even exceed the performance and specifications of their competitors.

For example, SLKOR's driver IC SL27511 (SOT-23) is a replacement for Texas Instruments' UCC27511DBVR, and the SLKOR driver IC SL27517 (SOT-23) is equivalent to TI's UCC27517DBVR. These driver ICs offer a direct pin-to-pin substitution while maintaining similar or superior performance characteristics. 

SLKOR offers a wide range of power management and driver ICs that are designed as pin-to-pin replacements for products from leading brands, such as ON Semiconductor, Diodes, Texas Instruments (TI), STMicroelectronics, Infineon, and others. Some of the key SLKOR products include:
