Application Notes (Cont’d):
Line Output (Pin14)
It is an open collector output which is able to drive a pulse current of 800mA for a rapid discharging
of the darlington base. The output pulse time is 22
µs for a 64µs period.
Frame Oscillator
The oscillator thresholds are internally fixed by resistors. The oscillator is synchronized during
the last half free run period. The input current during the charge of the capacitor is less than
100nA.
Frame Output Amplifier
This amplifier is able to directly drive the frame yoke. Its output is short circuit and overload
protected; it contains also thermal protection
