It integrates a 1.224V voltage reference, an  
amplifier, and an open collector output transistor  
in a single package. The TS4431’s operating  
mode is similar to the well-known standard  
voltage reference, the TL431. It maintains the  
desired feedback voltage at the REF pin in a  
closed loop configuration by sinking a current  
proportional to the error voltage at the REF pin.

Applications  
TS4431 features an open collector transistor with  
an ultra-low saturation voltage, allowing it to be  
used in series with the optocoupler in an SMPS  
architecture to regulate low voltage SMPS.
