MagnaChip Introduces a Step-Down DC/DC Converter for Smartphone Power Amplifier Applications
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 introduced a step-down DC/DC converter (model: MAP7153) designed to improve smartphone power amplifier performance and efficiency.
The MAP7153 optimizes power efficiency and extends smartphone battery life by converting output voltage into bypass or high voltage while operating in high power mode, or into low voltage while in low power mode.
The MAP7153 features fast transition time, excellent line and load regulation, and minimum footprint as a result of its reduced die size and small 1.32mm x 1.27mm WLCSP package. Two switching frequencies are also selectable in the MAP7153. A 3 MHz option provides improved efficiency while a 6 MHz option saves printed circuit board space by utilizing smaller inductors.
"Customers are demanding increased performance and power efficiency from their smartphones," said H.K. Kim, EVP and General Manager of MagnaChip's Display and Power Solutions Divisions. "By incorporating our MAP7153 into their designs, smartphone manufacturers can continue to provide new and improved products that significantly enhance energy efficiency and battery capacity in the fast growing smartphone market."
