22 / 37 page  Measurement results AN4376 22/37 DocID025380 Rev 1 6.10 LED driver efficiency at different LED load number Figure 19 shows the efficiency versus the line. Figure 19. Efficiency versus AC line voltage at different LED load Varying the number of the LEDs , the efficiency remains comparable with the nominal load, of course increasing the load to 25 LEDs means increasing the converter output power till 11.5 W. Section 7.7: Thermal measurements on page 29 shows that the HVLED815PF device is not overeating and is able to support this load properly. Note: Important: In this design a sort of short-circuit protection has been previewed, the R25 and R26 in series with the diode have been added to sense the short-circuit of the output connectors. If this function is not needed, the two parallel resistors could be removed and the converter efficiency will increase of 1.5%. |
