Proper Cares in Using the LA7835

LA7835

Note 1) If horizontal components are mixed into pin 1, causing the interlace characteristic to worsen, provide

decoupling as shown above. The resistor value and capacitor value are shown as an example.

2) If oscillation occurs, connect the OSC blocking circuit as shown above.

However, if the deflection current increases, oscillation may not be blocked completely. In this case, change

the application circuit as shown below.

3) In some applications, the OSC blocking capacitor across pins 9 and 11 is connected across pin 9 and GND.

4) The threshold voltage on pin 2 is +VCC11/4. Set the input trigger level so that it intersects this threshold level.

The LA7835 operates on the negative transition of the trigger pulse.

5) Connect the radiator fin to GND.
