NXP LCD display backlight with integrated LED driver

NXP semiconductors (NXP Semiconductors N.V.; NASDAQ:NXPI) 3 channel LED driver UBA3077 introduced for LCD display backlighting. UBA3077 based on NXP GreenChipTM technology, to solve the switching mode fully integrated scheme, suitable for multi channel applications, to provide powerful support LED applications become mainstream TV and computer display backlight and the popularization of LED general lighting. Through the support of low current dimming, UBA3077 with an accurate constant current drive LED lamp string and improve the LCD display backlight function, improve the quality of the picture, including the depth of light. With up to 94% efficiency, designers can design a thinner, lower power consumption and better heat dissipation of the LCD panel, with a better contrast to create a more beautiful picture quality UBA3077. UBA3077 will be listed in the near future. NXP semiconductor lighting solutions division of marketing and business development director Jacques Le Berre said: "UBA3077 for LED backlight with the current and future market trends in design. LED can save a lot of energy consumption and has a lower cost of product life. UBA3077 helps to create bright colors and does not contain any harmful substances, is based on the GreenChip technology, energy saving and environmental protection chip. Highlights: NXP UBA3077 using CMOS50 power management (Power Management PM) process, especially high voltage for the integration of digital environment in the design, the power characteristics and complex digital processing technology the perfect combination, and provide first-class performance. - UBA3077 consists of three independent channels, each integration of the boost converter and power supply, make application design by LED for additional radiating lamp string does not match the voltage. - UBA3077 step-up converter and power supply using integrated MOSFET, help designers reduce the size and reduce the cost of application of external components. - UBA3077 has high linearity and precision dimming function can be output at less than 1% under the condition of deep dimming, is conducive to improving the quality of images. - UBA3077 for each channel collocation independent pulse width modulation (pulse width, modulation, PWM) control, providing highly accurate efficacy and light control. - 14 PWM dimming (PWM or generated internally generated by the system) up to 24kHz (duty ratio from 0.1% to 100%). - UBA3077 operating voltage range of 10V to 42V, can drive up to three groups (each group of LED lamp string lamp string composed of 20 LED), the rated current of each lamp string can be as high as 150mA. , UBA3077 automatically run through 400kHz or I2C bus control. - UBA3077 using HVQFN40 package, can achieve good cooling through PCB.
