Magnachip Unveils 650V High Voltage MOSFETs Targeted for the LCD Television and Monitor Market

SEOUL, South Korea and CUPERTINO, Calif., Oct. 3, 2011 — MagnaChip Semiconductor Corporation (“MagnaChip Semiconductor”) (NYSE: MX), a Korea-based designer and manufacturer of analog and mixed-signal semiconductor products, has launched a series of 650V High Voltage (HV) MOSFET products for use in LCD-TV and LCD monitor applications.

The 650V MOSFET is used as a power conversion part for Switched-Mode Power Supplies where flyback topology is adopted. The main applications are typically LCD-TVs and LCD monitors which require high-speed switching. In mission critical situations, the use of power supplies which incorporate the 650V HV MOSFET is essential to securing a stable and regulated supply of power, particularly in countries which experience frequent power supply disruptions.

With the launch of our new series of 650V MOSFETs, MagnaChip Semiconductor will be able to meet the growing customer demand for high voltage MOSFETs used in power supplies and other devices. This also broadens our portfolio of MOSFET products which will now range from 20V up to 650V devices.

HK Kim, Executive Vice President of MagnaChip’s Power Solutions Division said, “We will continue to expand our MOSFET market share and grow our Power Solutions business by accelerating the introduction of new and value added MOSFETs to meet the growing demand of our current and future customer base.”
