Driver Configurations 2.1 Description The SAW8KG0B emitter is designed to operate directly off of AC line power(e.g 120Vac, 230Vac) with a rectifier, linear circuits or capacitive circuits or switching circuits. 2.2 Linear Circuit A) Resistor Driving Circuit It is better to use higher than rated power resistors for reliability. The rated power of the resistor should be chosen based on the equation Irms(A)*Irms(A)*Resistor value(ohms). The normal power rating of a 3216 size resistor is 0.25W. If the power consumption in one resistor exceeds the rated power of the resistor it is suggested to use multiple resistors in parallel. (a) Series configuration (b) Parallel configuration Figure 3.

This Configuration has the same current shape through the 5630 package as the standard AC drive (as seen in Figure 7), but since it can only drive one LED string it is very suitable for compact designs. Additionally the circuit efficiency is very high. You can also improve efficiency a little by eliminating the output resistor(Rout), but SSC recommends using Rout for surge immunity. Figure 7.
