The "LM2755" features a programmable function that can drive independent 3-lamp RGB LED products and white LED products. It is suitable for backlight display and has brightness adjustment function. The small size of the product is available in an ultra-thin micro SMD package that does not exceed 12 square feet.
In terms of power output, it can provide high-power current, and it is also suitable for lighting functions such as keyboards, and can use USB On-The-Go to obtain power for peripheral devices.
In addition, National Semiconductor has also introduced the "LM4510", which is capable of handling an organic EL screen display (OLED) device that is thinner than a liquid crystal display, providing up to 85% efficiency, and the product is a small LLP package specification. The three products have officially started shipping. When the price is in thousands, the unit price of "LM2755" and "LM2757" is 1.50 US dollars, while the "LM4510" is 1.80 US dollars.
