Description and Introduction

Energy Efficient, Off-Line Switcher with Enhanced Flexibility and Extended Power Range The TNY277GN is a member of the TinySwitch-III family of energy-efficient, low-power offline switcher ICs manufactured by Power Integrations. Below are the factual specifications, descriptions, and features:

### **Manufacturer:**  
Power Integrations  

### **Specifications:**  
- **Input Voltage Range:** 85 V AC to 265 V AC  
- **Output Power:** Up to 10.5 W (universal input)  
- **Switching Frequency:** 132 kHz  
- **Efficiency:** >70% (typical)  
- **Maximum Duty Cycle:** 72%  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package:** SMD-8 (DIP-8C)  

### **Descriptions:**  
- The TNY277GN is a highly integrated offline switcher IC designed for low-power applications.  
- It combines a high-voltage power MOSFET, oscillator, high-voltage switched current source, and control circuitry in a single chip.  
- It operates in a simple, cost-effective flyback topology.  
- Features auto-restart protection for overload, output short-circuit, and open-loop conditions.  

### **Features:**  
- **Energy-Efficient:** Meets global energy efficiency standards.  
- **Integrated MOSFET:** 700 V power MOSFET for reduced external component count.  
- **Frequency Jittering:** Reduces EMI filtering requirements.  
- **Auto-Restart Protection:** Safeguards against faults.  
- **Line Under-Voltage Detection (UVLO):** Ensures stable operation.  
- **Thermal Shutdown:** Prevents overheating.  
- **Burst Mode Operation:** Enhances efficiency at light loads.
