General Description

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;
