KEC supplies low-voltage MOSFETs to leading LCD manufacturers in Korea
KEC, a company specializing in power semiconductors, said that it is supplying low voltage MOSFETs to leading LCD manufacturers in Korea, and that it is scheduled to supply them by 2023, starting with the second half of 2020.
The low-voltage MOSFETs being supplied are applied to the timing controller board (hereafter T-CON board) parts that are mounted on the LCD of all-in-one PCs of global brand manufacturers. The T-CON board is a device that converts input image data into signals required by DDI (Display Driver IC), and is a key part that helps realize smooth synchronization by precisely controlling high-speed modulation of LCD pixels and backlight LEDs. In addition to the low-voltage MOSFETs for the T-CON board, KEC is in the process of mass-producing five components including a switching diode and a schottky barrier diode.
This KEC's low voltage MOSFET is a 100V product to which KEC's trench technology is applied, and it is specialized for LED lighting applications where a diode for ESD protection is built in the gate for static electricity protection. Moreover, even with a logic level (5V) driving voltage, the MOSFET performance can be sufficiently realized. This product is the first series of 100V MOSFETs applied to the SOT-23 package, and various package series are provided with the same chip. The small-signal products supplied with it are also specialized for low-voltage battery systems by boasting their performance even with a low driving voltage.
Park Nam-gyu, CEO of KEC Business Headquarters, expressed confidence in the quality, saying “The low-voltage MOSFET products being supplied are applied to the world's highest quality LCD products. KEC pursues high quality standards and product reliability. As a result, global electronics manufacturers in Korea with stringent quality standards have been working with KEC for a long time.”
