... Description 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 operational amplifier, makes it an ideal voltage controller ...

... Cs 240mV Ictrl Fig.1 Typical Adapter or Battery Charger Application Using SE1051 In the above application schematic, the SE1051 is used on the secondary side of a flyback adapter (or battery charger) to provide an accurate control of voltage and current. The above feedback loop is made with an optocoupler. Revision 12/4/2008 Preliminary and all contents are subject to change without prior notice. ...

... If the primary current limitation is considered not to be precise enough for the application, then a sufficient supply for the SE1051 has to be ensured under any condition. It would then be necessary to add some circuitry to supply the chip with a separate power line. This can be achieved in numerous ways, including an additional winding on the transformer ...
