National Semiconductor's new LED driver with dynamic headroom control

    National Semiconductor has introduced the LM3492 LED driver with dynamic headroom control to efficiently control the brightness of the two sets of lamps and ensure that the drive currents of the two sets of lamps are exactly the same. At the same time, it can greatly improve system efficiency, simplify circuit design, and reduce system cost. It belongs to National Semiconductor's PowerWise high energy efficiency chip series.

    The LM3492 chip has dynamic headroom control function, which can flexibly adjust the LED power supply by using the feedback voltage of the boost converter to achieve the lowest power consumption, so that the system can achieve the highest efficiency. Monitors of different sizes can be driven by a variety of different sizes of monitors using the LM3492 chip with dynamic headroom control. It is an ideal driver for automotive LCD backlight systems.

    At the same time, this driver has three MOSFETs built in, which simplifies circuit design and reduces system cost. The chip has a built-in boost converter and a dual-channel current regulator that can drive two sets of LEDs and independently adjust its brightness. The output power can be up to 15W, the output voltage is up to 65V, and it has high efficiency and cost. benefit.

    Programming Laptop

    There is a rule, custom laptop is called programming laptop cause nearly 90% is used for projects. 15.6 inch laptop for coding and programming is usually equipped with 10th or 11th cpu, 2gb or 4gb graphics optional. 15 inch laptop untuk programming is used on big tender or group for a special jobs. 15.6 inch programming laptop under 30000 is a more competitive one for business or high school students or teachers.

    However, here is the recommended laptop for programming, especially for heavy office jobs or university coursework, since double heat-releasing, metal body, bigger battery, FHD screen, high-level cpu, etc. Build the deep and stable foundation to enjoy smooth running experience. Your clients will satisfy it`s excellent performance. Of course, there are other lower specification with tight budget.

    As a entry windows laptop for programming, this 14 inch celeron Education Laptop is the most competitive and hottest device for elementary project.

    Any other special requirements, just contact us freely.
