Magnachip Mixed-Signal, Ltd. announced 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”), MMS has been developing and supplying a wide range of power ICs, including backlight 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 feature PMIC and level-shifter technology developed from Magnachip’s research and development activities since 2019. These products provide 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. The new PMIC enhances efficiency and reduces power consumption in applications, stably converting and distributing power required for the operation of high-end display panels in IT devices.

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

The IT display panel industry is expected to benefit from these new power solutions from MMS.
