STMicroelectronics TDA8172 - Vertical Deflection Booster

The TDA8172 from STMicroelectronics is a high-efficiency vertical deflection booster designed to drive the vertical deflection coil in a CRT monitor or television. This integrated circuit (IC) is a fundamental component for creating the vertical scanning in CRT displays, ensuring that the electron beam inside the CRT is moved correctly from the top to the bottom of the screen to create a visual image.

With its built-in pump-up circuit, the TDA8172 provides a high output current capability while maintaining low saturation voltage, enabling it to deliver a powerful performance that is ideal for high-resolution display systems. This feature helps in reducing power dissipation and improving overall efficiency, which is crucial for maintaining the reliability and longevity of the display unit.

The device is encapsulated in a 9-pin single in-line (SIP9) power package, designed for easy mounting and compactness, which is especially beneficial in applications where space is at a premium. It is capable of delivering a peak current of 2.5A, which is more than sufficient for most standard and even larger CRT displays.

The TDA8172 also features advanced protection systems, including thermal shutdown and guard circuitry, which protect the IC from over-temperature and short-circuit conditions. These protections ensure safe operation under a wide range of conditions and enhance the reliability of the final product.

Furthermore, the IC includes an internal flyback generator, which simplifies the circuit design by reducing the number of external components required. This not only saves space but also helps in reducing the overall cost of the vertical deflection solution.

Designed with the needs of modern CRT displays in mind, the TDA8172 is a testament to STMicroelectronics' commitment to providing high-quality, reliable components for the electronics industry. Whether for use in television sets, computer monitors, or other CRT-based applications, the TDA8172 stands out as an excellent choice for vertical deflection purposes.
