Figure 31. Isolated Output Line Powered Switching Power Supply
The above circuit shows the TLV431A/B as a compensated amplifier controlling the feedback loop of an isolated output line
powered switching regulator. The output voltage is programmed to 3.3 V by the resistors values selected for R1 and R2. The
minimum output voltage that can be programmed with this circuit is 2.64 V, and is limited by the sum of the reference voltage
(1.24 V) and the forward drop of the optocoupler light emitting diode (1.4 V). Capacitor C1 provides loop compensation.
