Magnachip Expands its LED Driver Product Portfolio to Notebook and Tablet PCs

SEOUL, South Korea and CUPERTINO, Calif., Oct. 31, 2011 — MagnaChip Semiconductor Corporation (“MagnaChip Semiconductor”) (NYSE: MX), an Asia-based designer and manufacturer of analog and mixed-signal semiconductor products, has launched a 4-channel LED driver for notebook computer applications and a 6-channel LED driver for tablet PCs.

The 4-channel LED driver, MAP3105, has an input voltage range of 4V to 26V and an embedded MOSFET which can boost output voltage to as much as 45V with a switching range of 500KHz ~2MHz. MAP3105 also maximizes LED brightness by increasing input current up to 40mA per channel, while minimizing current matching to less than 2% per channel. MAP3105 is offered in a TQFN-16L package and is 3mm x 3mm in size.

In addition, the 6-channel LED driver, MAP3106, has an input voltage range of 5V to 24V and an embedded MOSFET which can boost output voltage to as much as 40V with a switching range of 330KHz ~1MHz. MAP3106 is offered in a QFN package and is 4mm x 4mm in size.

Operating efficiency and safety have also been enhanced through a multitude of designed-in protection functions including current overload protection, LED open/short protection, over voltage protection, open Schottky diode protection among others. Detailed performance options and specifications can readily be found on the company’s website at www.magnachip.com.

H.K. Kim, Executive Vice President of MagnaChip’s Power Solutions Division said, “We are very pleased to have launched the fully integrated 4-channel and 6-channel LED backlight driver which expands our product portfolio of drivers for notebook and tablet PCs. Our goal is to continue to deliver leading-edge products by expanding our product portfolio with the latest in advanced technologies.”
