brief introduction:
July 20, 2007 - ON Semiconductor (Nasdaq: ONNN), the world's leading supplier of power semiconductor solutions, introduces the NCP5623, an energy-efficient three-output LED driver with an I2C interface, and Built-in progressive dimming function. The device is specifically designed to drive tri-color RGB (red, green, blue) LED decorative light and enhanced LCD backlighting in portable products such as cell phones and MP3 players. The NCP5623 is available in a compact LLGA-12 package and is the smallest RGB LED charge pump driver available in non-bump plastic packages on the market.
Manor Narayanan, vice president and general manager of Digital and Consumer Products at ON Semiconductor, said: "Portable products use LEDs to produce illuminating patterns that continue to enhance the appeal and interactive appeal of the products. ON Semiconductor's energy-efficient, ultra-small NCP5623 The LED driver's built-in unique control algorithm provides plug-and-play illumination for portable applications while supporting an extremely rich color mix."

The NCP5623 LED driver receives the processor's instructions through its I2C interface for automatic operation. Its three-way control current outputs are independent, each with a typical matching tolerance of ±0.5% and 32 current levels, allowing one tri-color RGB LED to display more than 32,000 colors. The device incorporates a progressive dimming function that gradually increases or decreases the output current to create a theater-like fade in/out effect. Thanks to the inclusion of a logarithmic current algorithm, the device ensures that brightness and color changes are presented in a smooth and gradual manner.
To maximize battery life, the NCP5623 achieves 94% peak energy efficiency and less than 1 microamp standby current, exceeding the operating range of a typical lithium battery. For typical applications, the device combines the advantages of a very small IC package with the ability to operate with only four passive components. The device also features short-circuit and over-voltage protection to protect the system from LED failure.
Package and price
The NCP5623 is available in a 2.0 mm × 2.0 mm × 0.55 mm LLGA-12 lead-free package and is priced at $0.55 per unit in 3,000-piece quantities.
