Application Information (cont.)

A second approach, shown in Figure 17, improves upon the method shown in Figure 16. Whereas the method in Figure 16 protects the light

engine, it will not function until the problem has been diagnosed and corrected.

The method shown in Figure 17 not only provides reverse polarity protection, it also corrects the reversed polarity, allowing the light engine to

function.

The BAS40BRW incorporates four low VF, Schottky diodes into a single package and allows more voltage available for the LED stack and

dissipates less power than standard rectifier bridges.
