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 V
CEO
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, this is illustrated in Fig.5 where
typical SOAR curves of the lower output transistor are given. 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.
Driver and switching circuit
Pin 1 is the input for the driver of the output stage. The signal at pin 1 is also applied to pin 3 which is the input of a
switching circuit (pin 1 and 3 are connected via external resistors).
This switching circuit rapidly turns off the lower output stage when the flyback starts and it, therefore, allows a quick start
of the flyback generator. The maximum required input signal for the maximum output current peak-to-peak value of 3 A
is only 3 V, the sum of the currents in pins 1 and 3 is then maximum 1 mA.
Flyback generator
During scan, the capacitor between pins 6 and 8 is charged to a level which is dependent on the value of the resistor at
pin 8 (see Fig.1).
When the flyback starts and the voltage at the output pin (pin 5) exceeds the supply voltage, the flyback generator is
activated.
The supply voltage is then connected in series, via pin 8, with the voltage across the capacitor during the flyback period.
This implies that during scan the supply voltage can be reduced to the required scan voltage plus saturation voltage of
the output transistors.
The amplitude of the flyback voltage can be chosen by changing the value of the external resistor at pin 8.
It should be noted that the application is chosen such that the lowest voltage at pin 8 is > 1,5 V, during normal operation.
Guard circuit
When there is no deflection current, for any reason, the voltage at pin 8 becomes less than 1 V, the guard circuit will
produce a d.c. voltage at pin 7. This voltage can be used to blank the picture tube, so that the screen will not burn in.
Voltage stabilizer
The internal voltage stabilizer provides a stabilized supply of 6 V to drive the output stage, so the drive current is not
affected by supply voltage variations.

SOLDERING
Introduction
There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and
surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for
surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often
used.
This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our
“IC Package Databook”
(order code 9398 652 90011).
Soldering by dipping or by wave
The maximum permissible temperature of the solder is 260 °C; solder at this temperature must not be in contact with the
joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds.
The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the
specified maximum storage temperature (T
stg max
). If the printed-circuit board has been pre-heated, forced cooling may
be necessary immediately after soldering to keep the temperature within the permissible limit.
Repairing soldered joints
Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more
than 2 mm above it. If the temperature of the soldering iron bit is less than 300 °C it may remain in contact for up to
10 seconds. If the bit temperature is between 300 and 400 °C, contact may be up to 5 seconds.
