1. Power Amplifier
2. Flyback Generator
3. Output Current up to 2 App
4. Thermal Protection

DC-coupled Application

1. When DC coupled (see Figure 4), the display vertical position can be adjusted with input bias. On the other hand, 2 supply sources (VS and -VEE) are required.

KA2133 datasheet

Description :

The KA2133 consists of a vertical system including an output function and a horizontal system in cluding an AFC function. It is for use in small size color TVs, B/W TV receivers and


1. Low power consumption, direct deflection coil driving capability
(Flyback voltage is two times as high as supply voltage is supplied during flyback period )

2. Variable circuit of vertical retrace time on chip.
