80% energy efficiency requirements, and asked for short-circuit and overvoltage protection and other protective features. in such applications, can be used from on semiconductor's ncp1015 chip switching power supply conol ic. this device integrates a fixed frequency (65/100/130 khz) current-mode conoller and 700 v high voltage mosfet, providing song building low-cost power supply all the necessary features, such as soft start, frequency jittering, short-circuit protection, skip-cycle, the maximum peak current setpoint and function of dynamic self-powered (no auxiliary winding) and so on. it is worth mentioning that, ncp1015 in the 1 w to 8 w led lighting applications, both can be used to isolated programs, can also be used for non-isolated solutions to meet different customer application needs. these two programs cost about the same.
led writing boardled white backlight which not only thermostable and ink will not crack, reflectivity more than 85%, while the thermal plastic itself is a heat sink, can reduce system temperature and the effective exclusion of heat. in addition, the anisoopic conductive adhesive bonding can be as long as the force a little artificial and natural curing at room temperature, so that lines in the vertical z-axis conduction, lateral is not turned on. this product is not suitable for high temperature hot eleconic products, and increase product yield.27-30 may 2010 fifteenth beijing essen welding & cutting fair was held in beijing, comau (comau) china's minisy of the body and robot welding business division together to participate in the exhibition, display comau in the automotive indusy and non-automotive indusy automation solutions. comau (comau) high-level .
led neon signled lighting applications is well known around the components, led lighting systems are more complex, involving optical, elecical and thermal various areas. semiconductor and eleconic products, as applied to the first green high-performance, energy efficient silicon solutions provider, to provide a complete led lighting solutions, in addition to driving power, but also include communications, optical sensors, mosfet, rectifiers, protection, filters and thermal management products, see figure 8. for example, led ambient light and seet light intensity conol, led display backlight intensity conol and white balance conol applications require very low power consumption of the ambient light sensors and light sensors to support the precise requirements of low light level, particularly in the presence of the case filter. in such applications, on semiconductor offers including light sensors, led drivers and high-speed i2c interface to the optical product portfolio, including optical sensors, including .
