SEA05 Datasheet (STMicroelectronics) - Advanced constant voltage and constant current controller

SEA05, Advanced constant voltage and constant current controller

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.
