Product overview
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, 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.
The external components needed to complete the two control loops are:
The TSM1052, housed in one of the smallest package available, is ideal for space-shrunk applications such as adapters and chargers.
