Sales Briefcase
  • The SEA05 is a highly integrated solution for SMPS applications requiring a dual control loop to perform CV (constant voltage) and CC (constant current) regulation.

    The device integrates a voltage reference, two opamps (with OR-ed open-drain outputs), and a lowside 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 and fixes the voltage regulation setpoint 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 setpoint and must be adequately rated in terms of power dissipation; the frequency compensation components (R-C networks) for both loops.
    The device, housed in one of the smallest available package, is ideal for space-shrunk applications such as adapters and chargers.

    Key Features

    • Open-drain output stage
    • Current sense threshold: 50 mV
    • SOT23-6L micro package

    • Low quiescent consumption: 200 µA
    • Wide operating VCC range [3.5 - 36] V
    • Voltage control loop accuracy +/- 0.5%
    • Low external component count
    • Voltage reference: 2.5 V
