产品概述

描述

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.
