TS4431 - 1.224V Open Collector Shunt Voltage Reference

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.

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. SOT23-5L (Plastic Micropackage) Pin connections (top view) 1 Vc c Sink 5 2 Gnd 3 Nc Ref 4.

TS4431 1.224V Open Collector Shunt Voltage Reference ■ Internal 1.224V ±0.5% precision ■ Low output saturation voltage 75 mV max between SINK and GND ■ Low current consumption: 250µA ■ 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.
