Description and Introduction

TOPSwitch -GX Family Extended Power, Design Flexible, EcoSmart, Integrated Off-line Switcher The TOP248F is a member of the TOPSwitch-Family of integrated switching power supply ICs, manufactured by Power Integrations.  

### **Specifications:**  
- **Input Voltage Range:** 85V AC to 265V AC (universal input)  
- **Output Power:** Up to 45W (depending on design and cooling conditions)  
- **Switching Frequency:** 132 kHz (fixed)  
- **Maximum Drain-Source Voltage (VDSS):** 700V  
- **Maximum Drain Current (ID):** 3.5A (peak)  
- **On-Resistance (RDS(ON)):** 2.6Ω (typical)  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package:** TO-220-7C (with full isolation)  

### **Descriptions:**  
The TOP248F integrates a high-voltage MOSFET, PWM controller, and protection circuits into a single IC. It is designed for offline flyback and forward converters, simplifying power supply design while improving efficiency and reliability.  

### **Features:**  
- **Integrated High-Voltage MOSFET:** Reduces external component count.  
- **Frequency Jittering:** Minimizes EMI emissions.  
- **Auto-Restart Protection:** For overload, open-loop, and short-circuit conditions.  
- **Soft-Start:** Reduces inrush current stress.  
- **Line Under-Voltage Detection:** Ensures stable operation.  
- **Thermal Shutdown:** Protects against overheating.  
- **EcoSmart® Technology:** Enhances energy efficiency.  

The device is commonly used in AC-DC power supplies for consumer electronics, industrial controls, and LED lighting applications.
