Description
The TS4436 is a four-terminal device dedicated to
low voltage Switch Mode Power Supplies
(SMPS).
It integrates a 0.6V voltage reference, an
amplifier, and an open collector output transistor
in a single package. The TS4436’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.
TS4436 features an open collector transistor with
an ultra-low saturation voltage. This feature allows
it to be used in series with the optocoupler in an
SMPS for regulation up to a 1.8V output voltage.
