MagnaChip Semiconductor Corporation (“MagnaChip”), a Korea-based designer and manufacturer of analog and mixed-signal semiconductor products, today announced the launch of a advanced 4-channel LED backlight unit (BLU) driver IC (Model: MAP3242) which features a 50% increase in driving power making it ideally suited for TV applications.


By combining the outstanding heat dissipation performance of a new heatsink small outline package (HSOP) with a programmable LED short protection function, MagnaChip was able to increase the output power level of its 4-channel LED by 50% to 60W(65V/240mA). This enables the MAP3242 to drive up to a maximum of 20 LED BLUs per channel, significantly increasing picture brightness while utilizing the same number of driver ICs as in existing display designs.


“The MAP3242 4-channel LED backlight unit driver was introduced for customers who demand an LED BLU driver IC that delivers superior performance and reliability,” said H.K. Kim, EVP and General Manager of MagnaChip’s Display and Power Solutions Divisions. “We are committed to delivering superior products targeting the growing LED TV market, particularly in China, where LED TV demand is soaring.”


Features of the MAP3242
• 4Ch LED Driver with internal dimming FET
• Wide input voltage range: 8.5V ~ 36V
• Max 200mA per channel
• 65V FB Pin Voltage
• 0.6V Min Headroom voltage @ 150mA
• LED current accuracy : ±2.5%
• Switching Frequency : 100kHz ~ 500kHz
• PWM and analog dimming
• Protections : LED Short (adjustable), LED Open OCP, TSD, UVLO
• Package : HSOP-28L, SOIC-20L, ETSSOP-20L
