Description and Introduction

LOW POWER OFF LINE SMPS PRIMARY SWITCH The **VIPER22ADIP** is a low-power offline switched-mode power supply (SMPS) primary switcher IC manufactured by **STMicroelectronics (STM)**.  

### **Key Specifications:**  
- **Package:** DIP-8 (Dual In-line Package, 8 pins)  
- **Input Voltage Range:** 9V to 38V (DC) or 85V to 265V (AC)  
- **Output Power:** Up to 8W (depending on configuration)  
- **Switching Frequency:** 60 kHz (fixed)  
- **Integrated Features:**  
  - High-voltage startup circuit  
  - PWM controller with current-mode control  
  - Built-in overvoltage protection (OVP)  
  - Thermal shutdown protection  
  - Auto-restart for fault conditions  
- **Operating Temperature Range:** -40°C to +150°C  

### **Description:**  
The VIPER22ADIP is designed for offline flyback and buck-boost converters, making it suitable for low-power AC-DC applications such as adapters, chargers, and auxiliary power supplies. It integrates a high-voltage power MOSFET (700V breakdown voltage) with a PWM controller, reducing external component count.  

### **Features:**  
- **High-Voltage Startup:** Eliminates the need for an external startup resistor.  
- **Current-Mode Control:** Ensures stable operation under varying load conditions.  
- **Low Standby Power Consumption:** Suitable for energy-efficient designs.  
- **Protection Mechanisms:** Includes overvoltage, overcurrent, and thermal shutdown.  
- **Soft-Start:** Reduces inrush current during startup.  

This IC is commonly used in cost-effective, compact power supply designs requiring minimal external components.
