PMIC for OLED display that enables a smooth and comfortable viewing experience, it supports a variable refresh rate from 60Hz~240Hz.
Magnachip’s power management IC (PMIC) is designed for IT devices equipped with OLED screens. The PMIC communicates with a system by using I2C protocol. Magnachip’s PMIC can control functions such as output voltage control, ON/OFF block, output voltage sequence management, protection circuit fault flag, and switching frequency transition. The fast transient response of this PMIC supports a variable refresh rate. This feature greatly reduces power consumption and enables a smooth and comfortable viewing experience for games and high-quality videos at refresh rates of 60Hz~240Hz.
“The expansion of OLED applications in IT devices is expected to continue,” said YJ Kim, CEO of Magnachip. “Magnachip will extend its premium PMIC product line through technological validation for a wide range of IT applications to address changing market demand and design requirements.”
According to the company, the fast transient response of this PMIC supports a variable refresh rate. This allows a screen to adjust how often it refreshes the image to match the frame rate without user input. This feature greatly reduces power consumption and enables a smooth and comfortable viewing experience for games and high-quality videos at refresh rates of 60Hz~240Hz.
The PMIC comes with various safety features including over-voltage protection, short circuit protection, thermal shutdown, under-voltage lockout, over-current detection, over-current shutdown and clamping circuit. Furthermore, Magnachip’s PMIC can control functions such as output voltage control, ON/OFF block, output voltage sequence management, protection circuit fault flag, and switching frequency transition. The PMIC is suitable for use in various battery-operated devices and handheld IT devices like laptops and tablets that are highly dependent on power efficiency.
