Power Management IC Optimized For OLED IT Devices

The PMIC for OLED display 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 with OLED screens. The PMIC communicates with a system by using the I2C protocol. Magnachip’s PMIC can control functions such as output voltage control, ON/OFF block, output voltage sequence management, circuit protection fault flag, and switching frequency switching. 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 by validating the technology for a wide range of IT applications to meet 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 has various safety features including over-voltage protection, short circuit protection, thermal shutdown, under-voltage lockout, over-current detection, over-current shutdown and clamping circuit. In addition, 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. PMICs are suitable for use in a variety of battery-powered devices and handheld IT devices such as laptops and tablets that rely heavily on power efficiency.
