Analogictech new show LED charge pump and battery charger IC

Due to popularity of portable electronic products, white LED backlight market to attract a large number of chip suppliers have introduced advanced charge pump products. Technologies Technology Co., Ltd. (Advanced Analogic) in the current IIC 2006 show a series of white LED backlight, OLED backlight charge pump products. Through the careful design of the power saving mechanism, charge pump of the company's products can provide high backlight power at the same time, to fully meet the needs of the portable electronic product color display.

Multi function, high efficiency dual charge pump AAT2803 support for portable systems (polymer lithium ion battery) white LED (light-emitting diode) backlight and camera flash applications. It can be controlled independently of three separate LED groups (two of which are used for backlighting, the other for camera flash), and are equipped with seven channels (one of the six for the backlight, the other for the camera flash). In addition, the handheld device AAT2803 is saving equipment two displays the power and space, and adding a light load mode (light load mode) on the handheld display in order to standby energy consumption will be reduced to a minimum.

For most handheld devices are equipped with two monitors: either flip design (main display, the second display), or vertical design (with the main display and backlight keyboard). The AAT2803 charge pump for two independent backlight group LED (with flash function) with mode control alone and light load, can help the designer to save energy and reduce the number of components and package size. These backlight products have been Samsung, LG and other brands of mobile phone use.

MP3 lithium ion charger IC is mainly used in handheld portable devices PDA, digital cameras, smart phones and other fields. But considering the increasingly fierce competition in the market and their market share tends to be stable, analogictech began to develop new products for Bluetooth applications, such as a new type of battery charger IC AAT3688 for Bluetooth applications.

AAT3688 is a highly integrated new battery charger IC, designed to run through the USB port input. As analogictech rapidly expanding BatteryManager series part of AT3688 is an innovative charge reduction loop, through the automatic monitoring of USB port voltage and current in the dynamic adjustment of the battery, shorten the charging time.
