Product overview
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.
