TECHNICAL DATA
VERTICAL DEFLECTION AND GUARD CIRCUIT (110°)
The KKA3654 is a full performance vertical deflection output circuit for direct drive of the deflection
coils and can be used for a wide range of 90 and 110 deflection systems.
A guard circuit is provided which blanks the picture tube screen in the absence of deflection
current.

FUNCTIONAL DESCRIPTION
Output stage and protection circuits
The output stage consists of two Darlington configurations in class B arrangement. Each output
transistor can deliver 1,5 A maximum and the VCEO is 60 V.
Protection of the output stage is such that the operation of the transistors remains well within the
SOAR area in all circumstances at the output pin, (pin 5). This is obtained by the cooperation of
the thermal protection circuit, the current-voltage detector and the short circuit protection.
Special measures in the internal circuit layout give the output transistors extra solidity. The same
curves also apply for the upper output device. The supply for the output stage is fed to pin 6 and
the output stage ground is connected to pin 4.

Notes
1. Non-repetitive duty factor 3,3%.
2. The maximum supply voltage should be chosen so that during flyback the voltage at pin 5 does
not exceed 60 V.
3. When V5-4 is 13 V and no load at pin 5.
4. Duty cycle, d = 5% or d = 0,05.
5. When pin 3 is driven separately from pin 1.
6. During normal operation the voltage V8-2 may not be lower than 1,5 V.
7. RL = 8  ; IL = 125 mA (r.m.s.).
8. If guard circuit is active.
9. With a 22 pF capacitor between pins 1 and 5.
