Description and Introduction

Energy Efficient, Off-Line Switcher with Enhanced Flexibility and Extended Power Range The TNY274GN is a member of the TinySwitch-4 family of integrated switch-mode power supply (SMPS) ICs manufactured by Power Integrations. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
Power Integrations  

### **Specifications:**  
- **Input Voltage Range:** 85V AC to 265V AC (universal input)  
- **Output Power:** Up to 5.5W in open-frame applications (230V AC)  
- **Switching Frequency:** 132 kHz (fixed)  
- **Efficiency:** Meets ENERGY STAR® and other global efficiency standards  
- **Maximum Duty Cycle:** 66% (auto-restart during fault conditions)  
- **Current Limit:** Adjustable via external resistor  
- **On-Chip Features:**  
  - 700V power MOSFET  
  - Auto-restart protection for overload, short-circuit, and open-loop conditions  
  - Line undervoltage (UV) and overvoltage (OV) protection  
  - Thermal shutdown  

### **Descriptions:**  
- The TNY274GN is a highly integrated offline switcher IC designed for low-power applications.  
- It combines a high-voltage power MOSFET, oscillator, control circuitry, and protection features in a single package.  
- Suitable for flyback converters in power supplies for consumer electronics, industrial controls, and appliances.  

### **Features:**  
- **Energy-Efficient:** Low no-load power consumption (<30 mW)  
- **Simple Design:** Requires minimal external components  
- **Protection Features:**  
  - Hiccup-mode overload protection  
  - Line-compensated current limit  
  - Thermal shutdown with hysteresis  
- **Package:** 8-pin DIP (through-hole) or SMD (surface-mount) options
