Description and Introduction

Enhanced, Energy Effi cient, Low Power Off-line Switcher The TNY268G is a member of the TinySwitch-II family of integrated circuits (ICs) manufactured by Power Integrations. Below are the key specifications, descriptions, and features based on factual information:

### **Manufacturer:**  
- **Power Integrations**  

### **Specifications:**  
1. **Input Voltage Range:**  
   - 85 VAC to 265 VAC (universal input)  

2. **Output Power:**  
   - Up to **9W** in open-frame applications (depending on design and conditions)  

3. **Switching Frequency:**  
   - **132 kHz** (fixed)  

4. **Efficiency:**  
   - High efficiency (typically >70%)  

5. **Current Limit:**  
   - Auto-restart protection with **cycle-by-cycle current limiting**  

6. **Operating Temperature Range:**  
   - **-40°C to +150°C** (junction temperature)  

7. **Package:**  
   - **DIP-8B (through-hole) or SMD-8B (surface-mount)**  

8. **Protection Features:**
