A8434
Overview
The A8434 high efficiency charge pump ICs offer a simple, low-cost WLED (white LED) driver solution for driving up to six WLEDs in various application configurations, either all six backlighting a single display, or for multiple displays, such as four WLEDs as the main display backlight, with the other two WLEDs used for backlighting a sub display or a low-current flash/torch. Using a proprietary control scheme (1×, 1.5×, and 2×), the A8434 can deliver well-matched WLED current while maintaining the highest efficiency and low EMI.
