  SE1051  Constant Voltage and Constant Current Controller Products Inquiry

    SE1051 is a highly integrated solution for SMPS applications requiring CV (constant voltage) and CC (constant current) modes.

    SE1051 integrates one voltage reference, two operational amplifiers (the outputs are OR’ed together, common collectors), and a current sensing circuit.

    The voltage reference, together with one operational amplifier, makes it an ideal voltage controller.  The other low voltage reference, together with another operational amplifier, makes it an ideal current limiter for low side output current sensing. The current threshold is fixed, and precise.

 

    The SE1051, housed in space-saving SOT23-6L package, is ideal for space sensitive applications such as adapters, cellphone chargers, Digital Camera chargers, and other battery chargers.
