TS4436 Adjustable 0.6V Open Collector Shunt Voltage Reference ■ ■ ■ ■ ■ ■ ■ Internal 0.6V ±0.5% precision Low output saturation voltage 75mV max. between SINK and GND Low current consumption: 150A Low supply voltage 1.7V Industrial temperature range: -40 to +85°C 150ppm/°C temperature coefficient Lead free available 1 PGND REF 5 SC70 (Plastic Micropackage) Pin connections (top view) 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. 2 GND 3 SINK V CC 4 Applications ■ ■ ■ ■ Low voltage switch mode power supplies Isolated DC/DC converter Computers Low voltage discrete regulators Order Codes Part Number TS4436AICT TS4436ICT Accuracy 0.5% -40, +85°C 1% SC70 Tape & Reel L21 Temperature Range Package Packing Marking L22 March 2006 Revision 1 1/8 www.st.com 8 Absolute Maximum Ratings and Operating Conditions TS4436 1 Absolute Maximum Ratings a……
