For the 3 channel LED driver display backlight NXP [LCD]

NXP semiconductors NXP Semiconductors N.V. recently announced the launch for the 3 channel LED driver UBA3077 LCD display backlight. UBA3077 GreenChip technology based on NXP, is a kind of switch mode of integrated solutions for multi channel applications, LED has become the mainstream television and computer display backlight, provides a powerful support and popularity of LED in general lighting applications. For the LCD display backlight, the UBA3077 can drive the LED lamp string with an accurate constant current, and improve the image quality by supporting low current dimming, including deep dark screen. With 94% energy efficiency, designers can use UBA3077 to design a thinner, lower power consumption, better heat dissipation LCD panel, with a higher contrast to create a more beautiful picture quality. UBA3077 upcoming. NXP semiconductor lighting solutions division of marketing and business development director Jacques Le Berre said: "UBA3077 for LED for the light current and future market trends and design. LED can save a lot of energy consumption, lower operating costs. UBA3077 is helpful to generate gorgeous color, and does not contain any harmful substances, is a kind of energy saving and environmental protection chip based on GreenChip technology. Features / highlights:? UBA3077 by CMOS50 PM (NXP power management) technology, designed for high voltage integrated in the digital environment and the characteristics of the power supply design, excellent and sophisticated digital processing technology perfect fusion, and can provide first-class performance by UBA3077? Three independent channels, each integrated boost converter and a current source, the application design from the LED lamp string voltage mismatch caused by extra heat? UBA3077 step-up converter and a current source with integrated MOSFET, can help designers to reduce the size, reduce the application cost of the external components UBA3077? Have high linear and precise dimming, dimming can be realized in less than 1% of the output light conditions, is conducive to improving the quality? UBA3077 collocation of independent PWM for each channel (pulse Width modulation) control, with high efficiency and precise control ability? 14 PWM dimming (generated by the system to generate PWM or 24kHz (internal) maximum duty ratio: 0.1% to 100%)? UBA3077 operating voltage range of 10V to 42V, can drive up to three 20 a group of LED lamp string, each lamp string rated current up to 150mA? UBA3077 can control operation or through the 400kHz I2C bus control? UBA3077 using HVQFN40 package, can achieve good cooling by PCB
