MagnaChip Semiconductor announced a new line of power management integrated circuits (PMIC) by introducing its first UHD display panel PMIC for laptops. 

MagnaChip’s PMICs are widely recognized in the industry for their advanced technology and outstanding quality. The newly released UHD display panel PMIC for laptops incorporates the company’s latest PMIC technologies. For instance, the new PMIC controls electricity consumption through I²C (Inter-Integrated Circuit) technology, which ensures that functions such as dynamic voltage management, on/off block, protection circuit fault flag and switching frequency transition in UHD display panels are performed seamlessly.

The new PMIC is a monolithic IC which includes 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 results in smaller and faster electronic circuits. Other features include ideal transient response and circuit protection measures. 

Per the company, the new PMIC can help address changes in current consumption and protects devices from damage with functions such as: over voltage protection, short circuit protection, under voltage lockout, over current detection, over current limit, and thermal shutdown. In addition, the new PMIC also offers constant current mode and dynamic switching frequency, which gives product designers more flexibility in meeting specific requirements of application.
