DOB IC solution will be the future of LED lighting driving development

What is a DOB IC ("De-power") ?

DOB (Driver on Board) or Driverless, which is what we usually call "de-power", is actually not without power supply, but a new driving method different from traditional switching power supply, which is derived based on LED characteristics. A new way of driving.

 

The DOB IC solution has many pioneers in the industry. There are mainly Seoul Semiconductor, British LynkLabs, Texas Instruments, and Exclara. In Taiwan, there are giants such as Industrial Technology Research Institute and Interlight.

 

There are many traditional power devices, large size and complex processing bring inconvenience to standardization, automation, and large-scale production.

 

Stability:

Due to the large number of components in the traditional power supply, the bad factor naturally increases. In particular, the life of electrolytic capacitors directly leads to an increase in the probability of failure of LED lamps. Although capacitors are used in valley filling in order to eliminate 100HZ power frequency flicker in DoB IC driver, these capacitors are fundamentally different from traditional power supply capacitors in specific applications. On the other hand, a capacitor failure in a linear valley fill will not result in a dead lamp. The failure of the capacitor in the traditional power supply directly leads to the dead lamp.

 

Smart Lighting:

From the perspective of intelligent lighting, linear IC driver has its inherent advantages compared with the traditional switching power supply driver. Smart lighting is also possible with conventional power supplies,but at a cost or system integration cost far beyond linear.

 

In terms of stability, safety, performance parameters and high cost, DOB linear IC is a cost-effective LED driver solution.
