Description and Introduction

SMPS PRIMARY I.C. The VIPER50ASP is a monolithic power IC manufactured by STMicroelectronics. It integrates a PWM controller and a high-voltage power MOSFET, designed for offline power supplies.  

### **Specifications:**  
- **Input Voltage Range:** 85V to 265V AC  
- **Output Power:** Up to 15W in flyback topology  
- **Switching Frequency:** 60 kHz (fixed)  
- **MOSFET:** 700V avalanche-rugged power MOSFET  
- **Current Sense:** Internal current sensing with cycle-by-cycle current limiting  
- **Standby Power Consumption:** < 1W (typical)  
- **Protection Features:** Overvoltage, overcurrent, thermal shutdown, and auto-restart  

### **Descriptions & Features:**  
- **Monolithic Design:** Combines PWM control and power MOSFET for compact offline power supplies.  
- **High-Voltage Startup:** Built-in high-voltage startup circuit eliminates the need for an external bias winding.  
- **Soft-Start:** Reduces inrush current during startup.  
- **Frequency Jittering:** Reduces EMI emissions.  
- **Eco-Mode Operation:** Improves efficiency at light loads.  
- **Package:** DIP-8 or SO-8 for easy PCB mounting.  

The VIPER50ASP is commonly used in AC/DC converters, adapters, and auxiliary power supplies.
