2582 / TDA2582 philips control circuit
Control Circuit for Power Supplies
The TDA2582 is a monolithic integrated circuit for controlling power supplies which are provided with the drive for the horizontal deflection stage.
The circuit features the following:
* Voltage controlled horizonal oscillator.
* Duty factor control for the negative-going transient of the out signal.
* Duty factor increases from zero to its normal operation value.
* Adjustable maximum duty factor.
* Over-voltage and over current protection with automatic re-start after switch-off.
* Counting circuit for permanent switch-off when n-times over-current or over-voltage is sensed.
* Protection for open-reference voltage.
* Protection for too low supply voltage
* Protection against loop faults
* Normal and smooth remote on/off possibilty.
And we salute our friends in other countries around the world!
