Overview
The TSM1014IDT, 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) control. This device is particularly suited for applications such as adapters and battery chargers, where precise voltage and current regulation are essential.
The TSM1014IDT integrates one voltage reference and two operational amplifiers. The voltage reference, combined with one of the operational amplifiers, functions as an ideal voltage controller. The other operational amplifier, along with a few external resistors and the voltage reference, can be used as a current limiter.
