FUNCTIONAL DESCRIPTION Vertical output Differential input amplifier The vertical output stage is a quasi-complementary class-B amplifier with a high linearity. The output contains SOAR (short-circuit protection) and thermal protection. The output current on pin 5 is reduced for a short time (to let the temperature decrease to Tj < 150 °C), when the junction temperature (Tj) exceeds 160 °C. The differential sawtooth input signal (coming from a ramp output of the TDA4850 for example) is fed to the input pins 2 and 3. The non-inverted signal is attached to pin 3. The vertical feedback signal is superimposed on the inverted input signal on pin 2. Vertical shift is applied at the inputs in a power-less way (see Fig.1). Deflection GUARD Pin 9 will go HIGH if the junction temperature goes to high (see Fig.3). A pulse signal with 50% duty cycle is output on pin 9, if the deflection coil is open-circuit. A flyback pulse signal is output at normal conditions. Flyback generator Signals for the flyback generator and the pulse circuit are generated in the flyback driver stage. The flyback output consists of a Darlington transistor and a flyback diode. The flyback generator can operate in two modes: Further watching can be achieved by means of an external GUARD circuit as shown in Fig.4. The 22 µF capacitor is charged during flyback time (V5 > V8) at normal conditions. In case of failures, the capacitor is discharged and the GUARD output goes HIGH. 1. An external supply voltage is applied for the short flyback time, thus the power dissipation is minimum (see Fig.1). GUARD output level (see Fig.4): 2. The flyback voltage is generated by doubling the supply voltage (see Fig.5). The 100 µF capacitor C2 between pins 4 and 7 is charged up to VP1 during scan, using the external diode and the resistor R2. The cathode of the capacitor C2 is connected to the positive rail during flyback. Thus, the flyback voltage is twice the supply voltage. 1997 Oct 27 • LOW for normal conditions • HIGH for deflection coil short-circuit respectively open-circuit • HIGH when there are neither input or output signals. 4 Philips Semiconductors Product specification Vertical deflection power amplifier for monitors TDA4860 LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 134); voltages referenced to substrate (pin 6); unless otherwise specified.

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. 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. 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. 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.
