Type Ordering Code Package
TDA 4601 Q67000-A2379 P-SIP-9-1
The integrated circuit TDA 4601/D is designed for driving, controlling and protecting the switching
transistor in self-oscillating flyback converter power supplies as well as for protecting the overall
power supply unit. In case of disturbance, the rise of the secondary voltage is prevented. In addition
to the ICs application range including TV-receivers video tape recorders, hifi devices and active
loudspeakers, it can also be used in power supply units for professional applications due to its wide
control range and high voltage stability during increased load changes.
