75 mV max between SINK and GND

■ Low current consumption: 250

µA

■ Industrial temperature range: -40 to +85°C

■ 100ppm/°C temperature coefficient

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
