Description
The TS4431 is a four-terminal device dedicated to
low voltage Switch Mode Power Supplies (SMPS).
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.
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.
Applications
■ Low voltage switch mode power supplies
■ Isolated DC/DC converter
■ Computers
■ Low voltage discrete regulator
