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.

Applications

■ Low voltage switch mode power supplies

■ Isolated DC/DC converter

■ Computers

■ Low voltage discrete regulators
