These programs provide our unique architecture lbl sophisticated steady flow, which makes LED lighting design is more flexible, and its jointly controlled method is applicable for future designs. "NCL30085, NCL30086 NCL30088 use power factor correction current control algorithm, making it suitable for flyback and buck - boost and single-ended primary inductance converter (SEPIC) lbl topology. These devices use quasi-resonant mode, it is possible to provide the highest energy efficiency in a wide range of AC voltage and load rating. They use innovative control method can be implemented separately from the primary side of the precise steady flow (typically less than 2%). Non-dimming NCL30088 and NCL30086 complement each other, which "may be wise dimming" support to control the average LED current single input analog and / digital pulse-width modulation (PWM) dimming. This series also includes NCL30085, this device supports three pairs of fractal light pace (70%, 25%, 5%). Accordingly, it can switch by switching the wall AC conduction / off state of signaling to the controller to reduce the LED current point, reduce the light output. All three devices include current thermal lbl foldback lbl user configurable mechanism to help prevent overheating, enabling manufacturers to support longer life warranty. NCL30085 and NCL30088 using SOIC-8 package, and NCL30086 using SOIC-10 package; this series lbl of products per unit in 10,000 unit quantities starts at $ 0.35. NCL30030 is a two-stage PFC controller and quasi-resonant flyback lbl controller optimized medium to high power LED lighting applications for up to 150 W of. This device is most suitable for commercial lighting, such as low-dome, high ceiling and lights. NCL30030 use proprietary multiplier architecture in the critical conduction mode (CrM) work, provide low harmonic distortion lbl and power factor close to 1. NCL30030 using SOIC-16 package, of which a pin is removed, for high-pressure pitch; each in 10,000 unit quantities starting from $ 0.65.
