ADI new white LED backlight driver ADP8860 come out

Analog Devices Inc. (ADI), the latest ADP8860 white LED backlight driver (WLED), which is the charge pump device configuration of the first series of new products, expand the lighting management system (LMS) product line. ADP8860 is designed for use with the LMS series of products, such as ADP5520 lighting management system and ADP5588 mobile I/O expander, it has registers ambient light sensor function, highly programmable and high gradient of light and brightness adjustment options, can significantly reduce the backlight power consumption up to 50%. This flexible architecture can simplify the system designer for a wide range of low power consumption, low voltage product optimization goal of power management, these products need to provide backlight for small size display consumption, medical, industrial and instrumentation in electronic devices and / or keyboard.

In areas such as shipping and navigation equipment, portable radar scanner and consumer mobile phone etc. these challenging applications need to achieve stable display in various lighting environment, ADP8860 can support 1.7 to 3.3 V I/O. The configurable architecture of the device can automatically detect the ambient light level and adjust the backlight brightness according to the changing light conditions. Other LMS devices and ADI company, ADP8860 LMS so that it can function as the light changes, the minimum gain automatically determine and adjust the required, under the same conditions, compared to the traditional charge pump device is the same light gain, it can reduce the power consumption of up to 50%. This product also provides multi area lighting to support the main screen and other displays, including navigation, special features, keyboard, indicator, and can significantly reduce power consumption while maintaining the necessary level of display light. LMS also helps to minimize the processor's participation, to extend the device's autonomy, that is to enhance the endurance, so that the battery usage time increased by 35%.

Single chip ADP8860 with parallel configuration function, can control up to 7 LED - 6 mA 30 LED (up) and a 60mA LED, providing advanced brightness adjustment and brightening / dimming function. This flexibility can be achieved by independent LED control to achieve the minimum / maximum current and the number of bright / dark times, or in the packet LED control allows the processor to eliminate the bright / dark task and save power consumption. For example, the designer can configure a small group of LED to provide backlight for the display, and assign a separate LED to drive the keyboard lighting and network connections, and charge the indicator light. Single chip ADP8860 backlight driver also enables system designers to quickly and easily upgrade to non LMS devices can provide advanced light color and brightness to the adjustment function, and prolong battery life, provide visual experience for enhancing media users in a variety of lighting conditions.
