Overview
The TSM101ID, produced by STMicroelectronics, is an integrated circuit designed to control voltage and current in switching power supplies. This IC incorporates a high stability series band gap voltage reference, two ORed operational amplifiers, and a current source. It compares the DC voltage and current level at the output of a switching power supply to an internal reference and provides feedback through an optocoupler to the PWM controller IC on the primary side. This component is essential for ensuring stable and regulated output in power supply systems.
