The TSM101/TSM101Aintegrated circuit incorporates a high stability series band gap voltage reference, two ORed operational amplifiers and a current source.
The TSM101 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 optocouplerto the PWMcontroller IC in the primary side.
The TSM101 can be used to modify the level of current limitation by offsetting the information coming from the current sensing resistor.
