Atmel released MSL2164 and MSL2166 16 series LED driver

Atmel Corp (AtmEL Corporation) announced the launch of the new 16 series LED series high performance driver, timing algorithm integration new product 3D can eliminate ghosting and flicker effect and improve the image quality of LCD TV. With these capabilities, Mel MSL2164 and Aite MSL2166 devices can be rolling in the new 3D and 2D backlight TV offers attractive viewing and video game experience.

The LED driver tinyAVR, and Mel megaAVR and AVR XMEGA's AVR microcontroller (MCU) seamless integration. The microcontroller handles timing and dimming commands and sends the data to the MSL2164 and MSL2166 devices. AVR devices and firmware provide an overall solution for optimizing the entire backlight design, providing superior performance compared to competitive solutions.

MSL2164 and MSL2166 devices with power management, the most efficient backlight control, as well as for multiple dimming mode 3D, scanning and regional light side light LCD TV, can drive up to 16 parallel LED series, to provide comprehensive system and fault management, to support the design of high performance backlight. The new driver series, high-end TV OEM manufacturers can use internal lighting timing algorithm to improve the timing precision of the backlight, providing more than other solutions on the market today to achieve high resolution, screen resolution, and significantly improve the image quality. At the same time, OEM manufacturers can choose the smaller size of the MCU, such as tinyAVR devices to reduce system overhead.

In the past, the TV OEM vendor had to calculate the appropriate parameters to effectively illuminate the required display backlight area. The LED driver will generate the algorithm to set the appropriate LED string phase to optimize the synchronization between the backlight and the LCD panel. OEM vendors must always perform additional algorithms to adjust the LED string phase to ensure that the backlight is fully synchronized during frame refresh. MSL2164 and MSL2166 have all kinds of pulse width modulation (PWM) mode, including forward, reverse, tail and center, as the new device integrated timing algorithm, design complexity can be reduced, which ensures that the best time is stable in all the backlight LCD pixel light.

"The next generation of TV, especially the TV with 3D screen, requires a different local dimming method," said Girish Art Mel, Ramesh's marketing manager for smart power. Our latest LED drives MSL2164 and MSL2166 have an intelligent timing algorithm and programmable PWM mode, for the development of LED side light TV OEM manufacturers provide a clear performance, design time and cost advantages.

Minimize power consumption and improve backlight performance

MSL2164 and MSL2166 devices with high current accuracy and LED matching to drive an external MOSFET, these devices have adjustable optical resolution Aite LED drive products in the series, Mel wide, can improve the contrast, compared with other solutions, reducing the power consumption of at least 20%.

12 bit PWM string dimming, you can achieve 4096 grayscale color, get a better image.

8 global brightness adjustment

12 bit PWM string adjustment (string phrasing)

10 bit digital to analog converter (DAC) current control to enhance dimming control under low light conditions

8 bit adaptive power correction is capable of maximizing the efficiency of up to three LED series power supplies.

On chip EEPROM allows OEM vendors to target critical system parameters, allowing the use of multiple sub frames to reduce overall system complexity and cost. The LED drive has an efficiency optimizer that adaptively controls up to three DC-DC converters for LED series power supply to minimize power consumption while maintaining LED current accuracy.
