Description

The TSM1052 is a highly integrated solution for SMPS applications requiring a dual control loop to perform CV (constant voltage) and CC (constant current) regulation.

The TSM1052 integrates a voltage reference, two op amps (with OR-ed open-drain outputs), and a low-side current sensing circuit.

The voltage reference is TSM1052 , along with one op amp, is the core of the voltage control loop; the current sensing circuit and the other op amp make up the current control loop.
