PMIC and level shifter for display panels in IT devices

Magnachip Mixed-Signal, Ltd. has released a multi-functional PMIC and a multi-channel level shifter to regulate different voltages and signals within display panels in IT devices.

For over ten years, the company has been developing and supplying a wide range of power ICs, including backlight unit LED drivers for TVs and LED lighting drivers. The quality of the company's products has been validated through successful cooperation with leading TV, OLED panel, and smartphone manufacturers, allowing it to expand its customer base globally.

The new products introduced provide PMIC and level-shifter technology stemming from the company's research and development activities since 2019. These technologies offer improved 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 improves efficiency and lowers power consumption in applications. Therefore, the power needed to operate high-end display panels in IT devices will be stably converted and distributed.

The new multi-channel level shifter is specially developed to regulate turn-on/off voltages for over 24 channels and efficiently manage voltage signals. Consequently, this level shifter fully fulfils the demanding channel needs of high-resolution displays and 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."
