Overview
The TSM1014AID, produced by STMicroelectronics, is a highly integrated solution designed for Switch-Mode Power Supply (SMPS) applications that require both constant voltage (CV) and constant current (CC) modes. This device is particularly suited for applications such as battery chargers and adapters, offering a compact and efficient solution for voltage and current control.
The TSM1014AID integrates one voltage reference and two operational amplifiers, making it an ideal component for precise voltage and current regulation. The voltage reference combined with one operational amplifier serves as a voltage controller, while the other operational amplifier can be configured as a current limiter using a few external resistors and the voltage reference.
