Description and Introduction

PWM Control IC for SMPS using MOS-Tra... The TDA4605 is a power supply control IC manufactured by SGS-THOMSON (now STMicroelectronics).  

### **Specifications:**  
- **Function:** Primary side control for switched-mode power supplies (SMPS).  
- **Operating Voltage Range:** Typically 8V to 12V.  
- **Switching Frequency:** Adjustable, typically up to 100kHz.  
- **Output Drive:** Direct drive for power MOSFETs.  
- **Protection Features:** Overvoltage protection, undervoltage lockout (UVLO), overcurrent protection, and soft-start.  
- **Package:** Typically available in DIP-8 or SO-8 packages.  

### **Descriptions and Features:**  
- Designed for flyback and forward converter topologies.  
- Includes a voltage regulator for stable operation.  
- Features a soft-start function to reduce inrush current.  
- Provides cycle-by-cycle current limiting for overload protection.  
- Suitable for use in TV power supplies, adapters, and other SMPS applications.  

For exact electrical characteristics, refer to the official datasheet from STMicroelectronics.
