Description and Introduction

PWM Control IC for SMPS using MOS-Tra... The TDA4605 is a control IC for switched-mode power supplies (SMPS), manufactured by Siemens (SIE).  

### **Specifications:**  
- **Operating Voltage Range:** 9V to 28V  
- **Standby Current:** Typically 3mA  
- **Operating Frequency:** Adjustable via external components  
- **Maximum Output Current (Driver Stage):** ±1.2A  
- **Soft-Start Function:** Integrated  
- **Overvoltage Protection (OVP):** Yes  
- **Undervoltage Lockout (UVLO):** Yes  
- **Thermal Shutdown:** Yes  
- **Package:** DIP-8 or SO-8  

### **Descriptions:**  
The TDA4605 is designed to control power MOSFETs or IGBTs in flyback or forward converter topologies. It provides a stable and efficient regulation mechanism for SMPS applications, including feedback loop control, oscillator timing, and protection features.  

### **Features:**  
- **Primary Regulation:** Direct feedback from auxiliary winding  
- **Soft-Start:** Reduces inrush current  
- **Overload Protection:** Prevents damage during excessive load conditions  
- **Frequency Jittering:** Reduces EMI emissions  
- **Adjustable Oscillator Frequency:** Set by external RC components  
- **Low Power Consumption:** Suitable for energy-efficient designs  

This IC is commonly used in power supplies for TVs, monitors, and other consumer electronics.
