DESCRIPTION

TJ1052 is a highly integrated solution for SMPS applications requiring constant voltage and constant current mode. TJ1052 integrates one voltage reference, two operational amplifiers (with one output - 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.
