TSM1051CD_02 Datasheet PDF - STMicroelectronics

DESCRIPTION
TSM1051 is a highly integrated solution for SMPS applications requiring CV (constant voltage) and CC (constant current) mode.
TSM1051 integrates one voltage reference, two operational amplifiers (with ORed outputs - common collectors), and a current sensing circuit.
The voltage reference combined with one operational amplifier makes it an ideal voltage controller, and the other low voltage reference combined with the other operational amplifier makes it an ideal current limiter for output low side current sensing.
The current threshold is fixed, and precise.
