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.

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.
