  • Low consumption voltage and current controller for battery chargers and adaptors
    TSM1012 is a highly integrated solution for SMPS applications requiring CV (constant voltage) and CC (constant current) mode. TSM1012 integrates one voltage reference and two operational amplifiers (with ORed outputs - common collectors). The voltage reference combined with one operational amplifier makes it an ideal voltage controller. The other operational, combined with few external resistors and the voltage reference, can be used as a current limiter.

  • Voltage and current controller
    The TSM101/TSM101A integrated circuit incorporates a high stability series band gap voltage reference, two ORed operational amplifiers and a current source. This integrated circuit (IC) compares the direct current (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.
