AS1109-BSST

AS1109 is a high-performance 8-channel parallel general-purpose LED driver, designed to meet the requirements of modern multi-LED display equipment. It is a low-cost, low-power, highly integrated device that is suitable for applications such as: LCD backlighting, LCD monitors and LCD TVs.

The most important features of the AS1109 are its high-precision, high-speed current regulation, and its flexible control system for multiple channels. The current regulation is achieved through Pulse Width Modulation (PWM) or Constant Current Regulation (CCR). PWM allows for fine-grained control, while CCR is more suited for high-precision, low-power applications.

The AS1109 also features high-efficiency current consumption and low power consumption. It is capable of delivering up to 3 watts per channel while consuming only 0.9 watts in total. This makes it extremely energy efficient and suitable for a wide variety of LED applications.

To control the LED switches and dimming, the AS1109 uses a dedicated 8-bit digital-to-analog converter. The converter is highly accurate, with a resolution of 0.02%, allowing for precise output control. The converter can be used to program any number of LED channels, from a simple single channel to a full 8 channel configuration.

The AS1109 features multiple operating modes, including PWM, CCR, and manual LED channel switching. It also supports thermal protection and over-temperature protection, ensuring that the LEDs stay at a safe temperature during operation. The device can be programmed with a wide range of frequency range and dimming curves, enabling precise control of the LEDs.

In addition, the AS1109 is an excellent choice for driving large LED displays. It is capable of delivering up to 6 watts of power per channel, and its digital-to-analog converter provides precise control over current regulation. This makes it ideal for LCD TVs, LCD monitors, and LCD backlights.

Overall, the AS1109 is a high-performance, low-cost, low-power LED driver, designed to meet the needs of modern multi-LED display equipment. With its precise current regulation, efficient energy consumption, and flexible control system, the AS1109 is the ideal choice for driving large LED displays.
