TDA4050B** is a monolithic integrated circuit manufactured by **Siemens** (now part of Infineon Technologies).

The TDA4050B is a monolithic integrated circuit manufactured by Siemens (now part of Infineon Technologies). It is designed for use in TV and monitor deflection systems, specifically for vertical deflection applications.

Key Specifications:

  • Supply Voltage (VCC): Typically 12V (max. 15V)
  • Output Current (Peak): Up to 3A
  • Power Dissipation (Pd): 15W (with heat sink)
  • Operating Temperature Range: -20°C to +85°C
  • Package Type: SIL-9 (Single In-Line, 9-pin)

Descriptions:

  • Designed for vertical deflection circuits in CRT-based TVs and monitors.
  • Includes internal thermal protection to prevent overheating.
  • Features a power amplifier for driving the vertical deflection coil.

Features:

  • High output current capability (up to 3A peak).
  • Built-in thermal shutdown protection.
  • Low external component count for simplified circuit design.
  • Suitable for 50/60Hz vertical deflection systems.

The TDA4050B is now considered obsolete, as CRT technology has largely been replaced by LCD/LED displays. However, it was widely used in older TV and monitor designs.

For exact datasheet details, refer to the original Siemens/Infineon documentation.
