This document introduces NXP Semiconductors' portfolio of LED solutions for gaming, mobile, signage, LCD TV backlighting, LED indication, and more. These solutions are designed for high performance, low cost, high power efficiency, and flexible design. They also include Fast-mode Plus, a wide supply range (2.3 to 5.5 V), and flexible PWM functions. They also have ultra-low standby modes (<1 µA), low CPU overhead, and extended battery life in mobile applications. These solutions also include application boards and daughter cards, and have a mature manufacturing infrastructure that supports high volumes. They provide everything you need to make lighting affordable, from mobile handsets and gaming systems to outdoor billboards, signage, and more.
This brochure presents NXP's portfolio of I²C‑bus LED driver ICs, highlighting power‑efficient designs, flexible PWM functions, and low‑standby‑current operation for a wide range of lighting applications. It includes application‑specific benefits for gaming, mobile devices, TV backlighting, and signage, as well as links to reference boards and high‑volume manufacturing capabilities.
The document details several product families such as the PCA962x, PCA963x, PCA9685, PCA9901, PCA9922/9926, and PCA953x/955x series, providing key specifications like supply voltage ranges, PWM resolution, interface speed, and output current capabilities. Packaging options and sales‑office information are also provided.
