LSI Delivers New Preamp IC for 2.5-Inch HDDs

LSI Corporation announced that its next-generation TrueStore PA2700 preamplifier integrated circuit (IC) is now sampling to select OEM customers. The PA2700 is a high-performance, low-power preamplifier IC specifically designed for use in 2.5-inch mobile hard disk drives (HDD) for the laptop computer market.

"LSI is committed to being the world’s leading HDD silicon provider and we continue to take solid steps toward achieving this goal," said Ruediger Stroh, executive vice president, Storage Peripherals Group, LSI. "We’ve seen consistent sales growth for our preamp products, and with four out of six of the industry’s leading HDD providers sampling the PA2700, we continue to build on this momentum. We now have preamp business and key design wins across all hard disk drive segments."

Designed using second-generation LSI silicon-germanium processes, the PA2700 delivers increased data rates and best-in-class write performance with operating speeds of up to 2.3 gigabits-per-second (Gbps), a performance increase of more than 50 percent over the previous generation. The PA2700 also offers an optimal balance of power, performance and reliability. The innovative power-saving features of the PA2700 help reduce power usage while the decreased heat dissipation delivers greater drive reliability.

The LSI family of ICs for hard disk drives includes read channels, preamplifiers, motor controllers, hard disk controllers and firmware, as well as highly integrated, high-performance storage systems-on-a-chip (SoCs). With these chips, manufacturers of hard disk drives get the performance and design flexibility needed to develop drives with outstanding storage capacity, speed, reliability and power savings.
