View Datasheet Manufacturer Site View Pricing & Stock

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: A resistor divider that senses the output of the power supply (adapter, battery charger) and fixes the voltage regulation set point at the specified value; A sense resistor that feeds the current sensing circuit with a voltage proportional to the dc output current; this resistor determines the current regulation set point and must be adequately rated in terms of power dissipation; Frequency compensation components (RC networks) for both loops. The TSM1052, housed in one of the smallest package available, is ideal for space-shrunk applications such as adapters and chargers.
