TDA8380-Switch Mode Power Supply for Control Circuits
Overview The integrated circuit TDA8380A is used as a low-cost control circuit for switching power supplies for televisions, monitors and small industrial equipment. Operates using the TDA8380A in fixed tax factor regulation frequency mode.
Features · A low current initialization circuit (150 mA max) that can be turned off · A bandgap reference voltage generator · Slow start of the circuit combined with accurate setting of maximum duty cycle (dMAX) · Programmable low voltage protection Provides a default value High power protection circuit Fault amplifier transfer characteristic with generator (TCG) Protection against open and short circuit feedback loops An overload voltage foldback A direct drive output stage (2.5 current sink, 0.75 output current)
Anti-Double Pulse Logic Protected from damage as a result of a short circuit to high voltage transistors Remote control oscillator and sync input
