Typical Forward Converter
Figure 7 shows a typical schematic for using the SRM4010 in an isolated Forward converter. The 5 volt output from the internal linear
regulator is used to provide power for the isolated optical feedback. Using the TLV431 outputs as low as 1.25 volts can be regulated
with the opto-coupler feedback.
