Control circuit for switched mode power supplies

GENERAL DESCRIPTION\nThe TDA8380A is an integrated circuit intended for use as a control circuit in low-cost switched mode power supplies for television, monitors and small industrial equipment. The TDA8380A operates using duty factor regulation in the fixed frequency mode. • A low-current initialization circuit (maximum 150 µA) which can be switched off\n• A bandgap reference generator\n• Circuitry for slow-start combined with an accurate setting of the maximum duty factor (Dmax)\n• Programmable low supply voltage protection with one default value\n• High supply prote;
