Figure 18. Flyback With Isolation Using TLV431, TLV431A, or TLV431B
as Voltage Reference and Error Amplifier
Figure 18 shows the TLV431, TLV431A, or TLV431B used in a 3.3-V isolated flyback supply. Output voltage VO
can be as low as reference voltage VREF (1.24 V ± 1%). The output of the regulator, plus the forward voltage
drop of the optocoupler LED (1.24 + 1.4 = 2.64 V), determine the minimum voltage that can be regulated in an
isolated supply configuration. Regulated voltage as low as 2.7 Vdc is possible in the topology shown in
Figure 18.
