The development of LED drivers faces two major technical obstacles

by:MOSO     2020-02-29
The development of LED drivers faces two major technical obstacles: heat dissipation and regression of size LED drivers are also greatly provoked. Since LED itself is a linear component, the main title currently facing is: **, the forward voltage changes with the change of current and temperature; Second, there will be differences in the forward voltage of non-conforming devices; Third, the color point will drift with the change of current and temperature; Fourth, the LED must be within the scope of the scale request to achieve a reliable task. The development of LED drivers faces * two major technical obstacles--Heat dissipation and size. Heat dissipation: the temperature of LED will be low at the time of obligation, so LED application needs to use energy-efficient power supply that will not aggravate the achievement of heat dissipation. Size: it is a continuous challenge to smoothly install the power supply into the LED lamp holder. PI's LED driver IC is extremely energy efficient and highly integrated, thus making it easy for prospective engineers to overcome the above two challenges. The technical difficulties of LED driving IC are high constant current accuracy, wide voltage scale of Vin, high voltage process of wafer and heat dissipation of MOS inside the chip. With the improvement of LED light-emitting chips, LED driving technology makes the power of LED more and more powerful and the brightness higher and higher, and its application is becoming more and more extensive. From the early instrument instigated to enter the LCD screen backlight, flashlight, car guidance, lighting, cover lights, etc. , to the general lighting field, such as table lamp, bedside lamp, fluorescent lamp and street lamp. In the future, LED driver IC will expand to more application fields.
