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.

LA78040 Datasheet PDF – Display Vertical Deflection Output IC

Part Number : LA78040

Function : TV and CRT Display Vertical Output IC with Bus Control Support

Package : TO-220-7H Type

Manufacturers : SANYO

Pinouts :

LA78040 image


Description :

The LA78040 is a vertical deflection output IC for high image quality TV and CRT displays that supports the use of a bus control system signal-processing IC. The sawtooth waveform from the bus control system signal-processing IC can directly drive the deflection yoke (including the DC component). Color TV vertical deflection system adjustment functions can be controlled over a bus system by connecting the LA78040 to a Sanyo LA768X series or LA769XX series bus control system signal-processing IC. Since the LA78040 provides a maximum deflection current of 1.8Ap-p, it is optimal for small and medium size CRTs.


1. Built-in pump-up circuit for low power dissipation.
2. Vertical output circuit.
3. Thermal protection circuit
