Magnachip Mixed-Signal Unveils Power Management IC and Level Shifter for Display Panels in IT Devices

SEOUL, South Korea–(BUSINESS WIRE)–Magnachip Mixed-Signal, Ltd. (“MMS” or the “Company”) announced today the release of a multi-functional Power Management Integrated Circuit (PMIC) and a multi-channel level shifter to regulate different voltages and signals within display panels in IT devices.

As a subsidiary of Magnachip Semiconductor Corporation (“Magnachip”) (NYSE: MX), MMS has been developing and supplying a wide range of power ICs, including back light unit LED drivers for TVs and LED lighting drivers, for over 10 years. The quality of the Company’s products has been validated through successful cooperation with leading TV manufacturers, OLED panel manufacturers and smartphone manufacturers, enabling MMS to expand its customer base globally.

The new products introduced today feature PMIC and level-shifter technology stemming from Magnachip’s research and development activities since 2019, and they provide the benefits of enhanced efficiency, low power consumption, multi-functionality and multi-channel capability.

The multi-functional PMIC was developed as a one-chip solution that integrates: a built-in controller, switches, logic circuit, two boost regulators, two negative low-dropout regulators, three high-current regulators for voltage down and two positive op-amps. With I²C*, this PMIC can control dynamic voltage management, a built-in on/off timer, protection circuits and switching frequency transition. As a result, the new PMIC enhances efficiency and reduces power consumption in applications. Therefore, the power required for the operation of high-end display panels in IT devices will be stably converted and distributed.

The new multi-channel level shifter is specially designed to regulate turn-on/off voltages for over 24 channels and efficiently manage voltage signals. Consequently, this level shifter fully satisfies the demanding channel requirements of high-resolution display panels and even UHD panels.

“We believe the IT display panel industry will benefit greatly from these new premium power solutions from MMS,” said YJ Kim, CEO of Magnachip. “We will continue the Company’s legacy of success with product development, production and technical support in a timely manner.”
