New PMIC for laptops with UHD display panels

The new PMIC manages electricity consumption through I2C technology, which guarantees that functions including dynamic voltage management, on/off block, protection circuit fault flag and switching frequency transition in UHD display panels are executed seamlessly.

The new PMIC is a monolithic IC which incorporates one boost regulator for the power supply to source and gate drivers, three high-current buck regulators for power supply to a timing controller, two Op-Amp for gamma buffer and one each positive and negative charge pumps. This level of integration produces smaller and faster electronic circuits. Other elements comprise fast transient response and enhanced circuit protection measures.

The new PMIC can help meet changes in current consumption and protects devices from damage with functions including overvoltage protection, short circuit protection, under voltage lockout, over current detection, over current limit and thermal shutdown. Also, the new PMIC provides constant current mode and dynamic switching frequency, which gives product designers more flexibility in satisfying specific needs of application.

“PMIC design requires sophisticated technologies, and we are proud to unveil our new PMIC for laptops, which incorporates our 10 years’ experience and technology leadership in the industry,” said YJ Kim, CEO of MagnaChip. “Our product roadmap will include possible expansion of our portfolio to address specialised display requirements from the tablet and OLED TV manufacturers, both of which are high growth potential markets.”
