The integrated circuit TDA4601D 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 IC's 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.
