MagnaChip Launches New Step-Down LED Backlight Drivers

Press release date: Feb 09, 2015

SEOUL, South Korea and CUPERTINO, Calif., – MagnaChip Semiconductor Corporation ("MagnaChip") (NYSE: MX), a Korea-based designer and manufacturer of analog and mixed-signal semiconductor products, today announced that it has launched two new step-down LED drivers targeting TV LED backlight and LED lighting applications. The new backlight drivers are designated as MAP3511 featuring single channel and MAP3512 featuring dual channels.

The MAP3511 and MAP3512 drivers are new designs which replace the existing step-up power circuit method of LED TV backlighting with a step-down circuit. These solutions enable the optimization of TV backlight power circuits by reducing system cost, such as eliminating the need for additional external MOSFETs for dimming control, and increasing system efficiency. The new products have multiple embedded protection circuits preventing functional errors during LED operation. This also enhances TV image quality and performance. In addition, a dimming function adjusts TV brightness and supports both PWM signal and analog dimming control signals, making it usable in a wide range of TV applications from low-end TV backlighting to premium ultra-high-definition (UHD).

HK Kim, Executive Vice President of MagnaChip's Power Solutions Division stated, "With the launch of two new step-down LED drivers, we continue to provide TV customers with high efficiency and cost effective solutions that will allow them to expand their market share in the global TV market."
