TI Launches Industry's Smallest Multiphase DC/DC Converter for Personal Electronics
Published2014.03.12 12:43
TI Korea (CEO Kent Chon, www.ti.com/ww/kr) March 11, 2014 – TI (CEO Kent Chon) has launched the industry's smallest 15A multiphase buck converter. The new LP8755 product extends battery life in smartphones and tablets while meeting the power requirements of advanced quad-core and octa-core processors. Additionally, the product features a total solution size of only 70mm², delivers up to 15A from 2.5V~5V input while achieving 90% efficiency. (For more information on samples and evaluation module orders, refer to www.ti.com/lp8755-pr)
The LP8755 with integrated FETs can manage dynamic voltage scaling (DVS) functionality that allows output voltage adjustment through two I2C interfaces, and automatically maintains the highest efficiency across the entire output current range by employing phase addition and shedding techniques. During light-load operation, the regulator enters low-power mode and consumes only approximately 10A (Iq) per core, maximizing light-load efficiency.
