STMicroelectronics expands Power-Supply Chips
The latest miniature power chip from STMicroelectronics is produced using an advanced technology that could see it used in nearly every new smartphone or small electronic device that has an AMOLED display.
ST already supplies over 80% of the world's ICs for powering AMOLED displays, which are ultra thin and promise even more vivid displays and wider viewing angles than today's LCDs. Increasing use in smartphones and other slim-line electronics such as digital cameras and appliance user interfaces will drive annual AMOLED shipments to $3.6 billion by 2015, from just over $600 million in 2008, according to analysts at IHS iSuppli; each AMOLED would require a driver/power-supply chip.
AMOLEDs have more complex power requirements than LCDs and need both a positive and negative voltage. ST's dedicated AMOLED power ICs adds value to new designs by simplifying power-supply circuitry. The new chip, the STOD13AS, is produced using ST's innovative Silicon On Insulator (SOI) process technology, which ensures outstanding energy efficiency and results in longer battery life. In addition, high immunity to cellphone-communication noise produces a consistent, flicker-free display.
