Description and Introduction

ICs for Consumer Electronics The TDA16846G is a power supply control IC manufactured by Infineon Technologies. Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Infineon Technologies  
- **Package:** P-DIP-14 (Plastic Dual In-line Package)  
- **Operating Voltage Range:** 8V to 28V  
- **Standby Power Consumption:** <1W  
- **Switching Frequency Range:** Adjustable (typically 20kHz to 200kHz)  
- **Output Current (Gate Drive):** Up to 1A  
- **Protection Features:** Overvoltage, undervoltage, overcurrent, and overtemperature protection  

### **Descriptions:**  
The TDA16846G is a monolithic integrated circuit designed for switched-mode power supplies (SMPS) in flyback or forward converter topologies. It provides control and protection functions for efficient power management in applications such as TVs, monitors, and other consumer electronics.  

### **Features:**  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Frequency Modulation:** Improves EMI performance.  
- **Adjustable Oscillator Frequency:** Allows optimization for different designs.  
- **Current Mode Control:** Ensures stable operation under varying loads.  
- **Low Standby Power Consumption:** Enhances energy efficiency.  
- **Integrated Protection Circuits:** Includes overvoltage (OVP), undervoltage (UVP), and overcurrent (OCP) protection.  

This information is based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

ICs for Consumer Electronics

Alternative Part Number

  • UC3842AN --: Industry-standard current-mode PWM controller widely used in offline SMPS, functionally similar to the TDA16846 controller and easy to source as a replacement.
  • NCP1200P60 --: Integrated offline PWM controller with built-in high-voltage startup, comparable application role in switch-mode power supplies and a common cross for Infineon TDA series controllers.
  • ICE3B0565J --: Infineon CoolSET offline PWM controller with integrated MOSFET, same manufacturer family and similar SMPS control function, suitable when a same-brand alternative is preferred.
