In production applications, it is important , which is equivalent to the system greatly reduces the LED Downlight risk of failure . Makes this solution not only in performance has been a qualitative leap in reliability is also greatly improved . DU8618 1A integrated high-voltage MOSFET, to achieve the ultimate in turn simplifies the circuit by a low current, high voltage design , reduce losses, let 1A MOSFET integrated package for small volume SOP8 in , you can do all of 18W or less non-isolated LED driver requirements.
Figure 5 linear regulation near 0 , it is because the chip -by-cycle loop control, immediately respond , will not cause the output current. In the realization of this ideal linear regulation , it is also obviates the second generation of linear compensation controller chip because many external components, a simple philosophy that is perfect in this design once again reflected.
Figure 6 : System load regulation
High load regulation is the practical significance of multiple sets of lights can set the power load . For example, about 36V output 12 series , 24 series output is about 72V , if the design of the current values are the same , can be used with a power supply, the power plant in the production of the preparation , inventory management, a significant value . It is worth mentioning that, in Figure 6 , the system is still achieved when the circuit constant , which means : 1. Circuit protection through the most secure manner. 2 This is the true meaning of full load constant .
