  • 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.

    Key Features

    • 1.24 V series voltage reference with 10 mA output current and 1% precision
    • Built-in current generator with enable/disable function
    • Two operational amplifiers with ored output and 1 MHz gain bandwidth product
    • SO8, DIP8 and TSSOP8 packages
    • 4.5 to 32 V supply voltage range
