Description and Introduction

LOW-NOISE TV VERTICAL DEFLECTION SYSTEM The TDA1170D is a vertical deflection output circuit manufactured by STMicroelectronics (ST).  

### **Specifications:**  
- **Type:** Monolithic integrated circuit  
- **Function:** Vertical deflection output for TV and monitor applications  
- **Supply Voltage (VCC):** 12V to 35V  
- **Output Current:** Up to 1.5A (peak)  
- **Power Dissipation:** 15W (with heat sink)  
- **Package:** SIP-9 (Single In-line Package with 9 pins)  
- **Operating Temperature Range:** -20°C to +150°C  

### **Descriptions:**  
- Designed for vertical deflection in CRT-based TVs and monitors.  
- Includes a sawtooth generator, power amplifier, and thermal protection.  
- Provides stable vertical scanning with minimal external components.  

### **Features:**

- Short-circuit protection  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics, refer to the official STMicroelectronics documentation.

Application Scenarios & Design Considerations

LOW-NOISE TV VERTICAL DEFLECTION SYSTEM

Alternative Part Number

  • LM317T --: Widely available adjustable linear regulator in a TO-220 package that can serve as a general-purpose replacement in many power supply designs, though pinout and function should be verified against the original vertical deflection IC.
  • TDA1170N --: Closely related vertical deflection IC from the same family with similar function and pinout, often used as a drop-in substitute where the D-suffix version is unavailable.
  • KA2131 --: Vertical deflection IC used in CRT monitor/TV applications with comparable functionality to the TDA1170 series, suitable as a cross-reference alternative after verifying pin compatibility.
  • TDA1175P --: Similar vertical deflection IC from ST with comparable function and output capability, commonly used in CRT TV deflection circuits.
  • LA7800 --: Alternative vertical deflection IC from a different manufacturer and series, functionally comparable for TV vertical deflection applications.
