Description and Introduction

Enhanced EcoSmart?, Integrated Off-Line Switcher with Advanced Feature Set and Extended Power Range The TOP256PN is a member of the TOPSwitch-HX family of integrated switching power supply ICs manufactured by Power Integrations.  

### **Specifications:**  
- **Input Voltage Range:** 85 VAC to 265 VAC (universal input)  
- **Output Power:** Up to 29 W (open-frame)  
- **Switching Frequency:** 132 kHz  
- **Maximum Drain-Source Voltage (VDSS):** 700 V  
- **Integrated MOSFET:** Yes  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package:** DIP-7 (Through-hole)  

### **Descriptions:**  
The TOP256PN is a highly integrated offline switcher IC that combines a high-voltage MOSFET, PWM controller, and protection features into a single package. It is designed for flyback and buck-boost converter topologies, commonly used in power supplies for consumer electronics, industrial controls, and lighting applications.  

### **Features:**  
- **EcoSmart® Technology:** Reduces standby power consumption  
- **Integrated Auto-Restart Protection:** For over-temperature, over-voltage, and output short-circuit conditions  
- **Frequency Jittering:** Reduces EMI filtering requirements  
- **Soft-Start:** Minimizes inrush current  
- **Cycle-by-Cycle Current Limiting:** Enhances reliability  
- **Line Under-Voltage (UV) and Over-Voltage (OV) Protection:** Ensures stable operation under varying input conditions  

This device is suitable for applications requiring compact, efficient, and reliable power conversion.
