2011年1月11日 · The ADM8845 provides the power required to drive up to 6 white LEDs, using charge pump technology. The LEDs are used for backlighting a color LCD display. To maximize power efficiency, a charge pump that can operate in either a 1x, 1.5x or 2x mode is used.

The ADM8845 uses charge pump technology to provide the power required to drive up to six LEDs. The LEDs are used for backlighting a color LCD display, having regulated constant current for uniform brightness intensity. The main display can have up to four LEDs, and the sub display can have one or two LEDs.

ADM8845利用电荷泵技术提供所需的2.6 V至5.5 V（锂离子）输入电源，最多可驱动6路白色LED。这些白色LED用于彩色液晶显示器的背光照明。为实现高的电源效率，采用能够以1x、1.5x或2x模式工作的电荷泵。
