Catalyst's new CAT3647 and CAT3648 chip brightness adjustment features provide enhanced LCD backlight control for emerging portable applications. It is launched to meet the needs of high-resolution LCD brightness control and extended battery life. Through programming capabilities, the step increment is only 3% of the interval. CAT3647 and CAT3648 provide designers with better LED current and brightness control for a richer user experience. This is all done through Catalyst's single-wire programmable interface (EZDimTM), which supports a total of 32 linear adjustments from full-bright to zero-current EZDimTM interface.
The new LED driver is a 4-mode fractional charge pump (1x, 1.33x, 1.5x, 2x) that provides 10% more conversion efficiency and no additional cost compared to a 3-mode charge pump. The CAT3647 drives up to 3 LEDs with a maximum current of 30mA per LED. The CAT3648 drives up to 4 LEDs. The maximum current per LED is 25mA. The power efficiency of both LEDs is up to 92%. CAT3647 and CAT3648 are now available. Join the Catalyst Quad-Mode LED driver family, including: CAT3604V four-channel LED driver with PWM dimming interface; CAT3636 six-channel LED driver with single-line EZDim interface and 32-level brightness adjustment;
CAT3644 four-channel LED driver with single-line EZDim interface, 6-level brightness adjustment and CAT3643LED three-channel LED driver; CAT3637 six-channel LED driver with single-line EZDim interface and 16-level brightness adjustment.
Samples and evaluation boards are now available for the CAT3647. Thanks to the ultra-thin 3mm x 3mm, 16-pin TQFN package, the new components save board space and cost, and compared to existing 3-mode LED drivers, four operating modes can be achieved without additional capacitors.
LED Lighting Cable:Form: socket, plug stamping injection molding, widely used for LED outdoor lighting waterproof plug, connector, power cord plug.
Product advantages: at present, LED outdoor waterproof male and female plug, waterproofing, waterproof power line, waterproof connection line, waterproof plug wire and so on have been widely used in society, mainly waterproof male and female plug, waterproofing, waterproof power line, waterproof plug wire, these products play the advantage of environmental protection and energy saving, and can play an anti ultraviolet, radiation protection, anti-oxidation, anti-aging in hot summer. Function, in the cold winter to play a moisture-proof, moisture-proof, cold-resistant effect, so at present this product has been through the national policy and has been strongly supported by the national policy.
