OKI Increases its Lineup of Power Management LSIs for Mobile Devices

“We entered the power management LSI market in July 2006 to leverage our strength in manufacturing technologies for high-voltage and lower power consumption devices, which are widely used in manufacturing processes and TFT LCD driver LSIs. The models we add today significantly reduce power consumption which means longer battery life for mobile devices,” said Takaki Yamada, President of Silicon Microdevice Company at Oki Electric Industry. “Going forward we will continue to provide various kinds of power management LSIs with a variety of functions, not only for mobile and portable devices but also for flat panel displays and printers.”

Mobile devices, such as mobile phones, are becoming sophisticated with built-in camera, music player, TV tuner for one-segment broadcasting and capability for handling electronic money — all of which require longer batter life. OKI’s news LDO1 regulator provides power consumption of 50-100nA in standby mode and 3-12μA in no-load mode. This is an 80-90% reduction in power consumption compared to the industry standard, and is ideal for sophisticated mobile devices. The efficiency of OKI’s step-down DC/DC converter is 95% at an output current of 500mA, which is higher than conventional converters, thus offering an attractive solution as the main power supply for digital still cameras.
