Product overview
Description
The TSM101/TSM101A integrated circuit incorporates a high stability series band gap voltage reference, two ORed operational amplifiers and a current source.
This IC compares the DC voltage and the current level at the output of a switching power supply to an internal reference. It provides a feedback through an optocoupler to the PWM controller IC in the primary side.
The controlled current generator can be used to modify the level of current limitation by offsetting the information coming from the current sensing resistor.
