LA7836
Vertical Deflection Output Circuit with Driver for TV Sets and Monitors
Overview
The LA7836 is an IC that contains the vertical deflection output circuit with a driver for color, B/W TV sets, monitors, and display units with a large aperture (maximum deflection current 2.2Ap-p) and is placed in an SIP13H package. The LA7836 features fewer external parts and low power dissipation. Since both DC feedback and AC feedback can be provided inside the IC, it is easy to design the vertical deflection circuit. The LA7836 can be used in conjunction with single-chip IC LA7650 series (NTSC), LA7680 series (PAL/NTSC) (VIF, SIF, video, chroma, and deflection circuit) to provide all the functions required for color TV signal processing.

Proper Cares in Using the LA7836
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 +VCC1/4. Set the input trigger level so that it intersects this threshold level. The LA7836 operates on the negative transition of the trigger pulse. 5) Connect the radiator fin to GND.

Specifications of any and all SANYO products described or contained herein stipulate the performance, characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer's products or equipment. To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer's products or equipment. SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all semiconductor products fail with some probability. It is possible that these probabilistic failures could give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire, or that could cause damage to other property. When designing equipment, adopt safety measures so that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective circuits and error prevention circuits for safe design, redundant design, and structural design.
