Using new LED drivers to meet the needs of high-performance multimedia mobile phone designs Using new LED drivers to meet the needs of high-performance multimedia mobile phone designs After several years of development, mobile phones have evolved from mainly voice applications to comprehensive multimedia platforms. Mobile phone users can use their phones to exchange text messages, read and write emails, share photos, browse the Internet, shoot video clips, and even use their phones to activate the global positioning system (GPS) for entertainment, driving, and consumer positioning. To help mobile phone designers develop products that are more suitable for these new applications, Leadis Technology Inc. provides a series of LED drivers that support large screens and have high performance. Compared with other drivers, Leadis\' innovative 1.33 times charge pump and PowerLite rectifier LED driver can effectively improve efficiency by 20%, meeting the market\'s design needs for large screens. The following is a wonderful question and answer about Leadis\' new LED driver. Q: What are the obvious differences between the new driver and the ordinary products currently in use? A: The new driver we are using now has three features: First, the 1.33 times boost mode can increase the efficiency of the product by 10%; second, the PCR function, that is, a new internal rectifier is integrated into the LED driver, which can reduce the internal voltage drop of the IC from 200MV to 50MV, and the efficiency can be increased by 10%; third, the NVM function, we can pre-set the current value into the IC according to the customer\'s requirements, so that when the IC is started in the future, there will be a predetermined value, and the customer does not need to assign the IC, and the IC can automatically output the specified current value, which is more convenient to use. Q: In addition to meeting the design requirements of high-performance multimedia mobile phones, what other areas can the new driver be applied to, and what are the advantages of application in various aspects? A: From the current point of view, in addition to being used in mobile phones, it can also be used in a series of handheld devices with LED screens such as portable DVD, MP4, GPS, etc. Q: How much power does the new driver consume? What is the difference in design from previous drivers? Are there any special requirements? A: The power consumption of the new driver is very small, only about 1μ, and the maximum can reach 120MA. When customers design new drivers, the design method is exactly the same as the common design methods on the market, including interface and hardware design, and there are no special requirements. Q: Will the new driver increase...
