SEOUL, South Korea and CUPERTINO, Calif., Jan. 30, 2012 /PRNewswire/ — MagnaChip Semiconductor Corporation (“MagnaChip”) (NYSE: MX), a Korea-based designer and manufacturer of analog and mixed-signal semiconductor products, and GMT (Global Mixed-mode Technology), a leading fabless provider of power solutions for mobile phone and PC applications, today announced that MagnaChip has ramped to mass production GMT’s power management IC (PMIC) products utilizing 0.35um BCD (Bipolar CMOS-DMOS) process technology.

MagnaChip and GMT have been engaged in the development of PMIC and LED Driver IC products using 0.35um 65V BCD process technology at MagnaChip’s manufacturing facility located in Cheongju, South Korea. MagnaChip has successfully completed the final qualification of PMIC products which have ramped to high-volume production, while the LED driver IC products are currently under development.

The PMIC manages multiple power levels for LCD TV and monitor applications. GMT’s PMIC incorporates a high-performance linear regulator, low-power charge-pump regulators, a high current operational amplifier and a logic-controlled gate-on pulse modulator to control the positive charge-pump output sequence and waveform. MagnaChip is uniquely positioned as a foundry provider to be able to offer the deep trench isolation technology for PMIC applications.

In addition to the PMIC, GMT’s LED Driver IC has the ability to drive up to 12 parallel strings of LEDs at a maximum of 120mA of current. It also provides a precision current balance function for each LED string. Additionally, the LED string voltages can be up to a maximum of 65V. This makes it very suitable to be used in main stream (40 inch ~ 55 inch) LED TV back light applications.

Namkyu Park, Vice President of MagnaChip’s Foundry Marketing commented, “We are very pleased to announce MagnaChip’s production ramp of GMT’s PMIC products using our 0.35um BCD process technology. The continued introduction of these robust PMIC solutions is a direct result of the combined expertise of MagnaChip’s manufacturing services and GMT’s design engineering. We will continue to develop highly differentiated and cost-effective BCD technology solutions to meet the increasing application specific needs of our foundry customers.”

MagnaChip Semiconductor Corporation (“MagnaChip”) (NYSE: MX) today announced that its Korean subsidiary has entered into a definitive agreement to acquire Dawin Electronics Co. Ltd., a privately held semiconductor company that designs and manufactures Insulated Gate Bipolar Transistor (IGBT), Fast Recovery Diode (FRD) and MOSFET modules. Dawin Electronics is headquartered in Incheon, South Korea, and has sales offices in China and Europe. Terms of the deal were not disclosed.

“The acquisition of Dawin Electronics is a strategic fit for MagnaChip and allows us to continue to diversify and expand our fast-growing Power Solutions business into the commercial and industrial segments,” said Sang Park, MagnaChip’s Chairman and CEO. “Dawin’s high-power modules will enable MagnaChip to compete quickly and effectively in the high-growth IGBT market with a broader portfolio of power solutions for our customers. This acquisition also demonstrates our continued focus on capital allocation and commitment to return shareholder value to our investors.”

According to market research firm IHS iSuppli, the total IGBT market in 2011 was estimated to be $4.1 billion and is expected to grow at a compounded annual growth rate of 10 percent from 2011 to 2015. The IGBT is used in a broad range of medium- to high-power commercial and industrial applications and in many consumer appliances such as variable speed refrigerators, air-conditioners and stereo systems. Availability of affordable, reliable IGBTs is also an important enabler for electric vehicles and hybrid cars.

The acquisition of Dawin and its IGBT and FRD module technology is synergistic with MagnaChip’s goal of expanding into high-growth, high-margin markets and with its long history as a designer and manufacturer of analog and mixed-signal semiconductor products. The acquisition is expected to be completed before the end of March 2012.
