Eight New Power Management LSIs for Mobile Devices, launched by Oki
Oki Electric Industry, has unveiled eight new models of power management LSIs specifically for mobile devices. The new launch has the ability to provide low power consumption, low noise and high efficiency.
Now-a-days, mobile phones feature high-end functionalities such as built-in camera, music player, TV tuner for one-segment broadcasting and capability for handling electronic money. To operate all the above mentioned specs, it is necessary for the phone to deliver longer battery life. Thus, the handset should have enough power to manage all the features.
“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 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,” stated Takaki Yamada, President of Silicon Microdevice Company at Oki Electric Industry.
Oki has introduced its latest LDO (low drop out) regulator that offers power consumption of 50-100nA in standby mode and 3-12μA in no-load mode. A perfect solution for full-fledged functionality mobile phones, the Oki LSI reduces about 80 percent – 90 percent of power consumption as compared to the industry standard.
The competence rate of Oki’s step-down DC/DC converter is 95 percent at an output current of 500mA, which is higher than traditional converters. It provides an interesting solution as the main power supply for digital still cameras.
