Description and Introduction

OFF LINE PRIMARY SWITCH The VIPER53DIP is a high-voltage converter manufactured by STMicroelectronics. It is part of the VIPerPlus family, designed for offline power supplies.  

### **Specifications:**  
- **Input Voltage Range:** 9V to 38V (DC)  
- **Output Power:** Up to 13W (in flyback topology)  
- **Switching Frequency:** 60 kHz (fixed)  
- **Integrated Power MOSFET:** 800V avalanche-rugged  
- **Current Mode Control:** Yes  
- **Protection Features:**  
  - Overvoltage protection (OVP)  
  - Overcurrent protection (OCP)  
  - Thermal shutdown  
  - Undervoltage lockout (UVLO)  
- **Package:** DIP-8  

### **Description:**  
The VIPER53DIP is a monolithic IC combining a PWM controller and an 800V power MOSFET, optimized for offline flyback converters. It operates in current-mode control for stable performance and includes multiple protection features for reliability.  

### **Features:**  
- **High-Voltage Startup:** Internal startup circuit eliminates the need for an external resistor.  
- **Low Standby Power:** <30mW in no-load conditions.  
- **Soft Start:** Reduces inrush current.  
- **Frequency Jittering:** Minimizes EMI emissions.  
- **Auto-Recovery Protection:** Safely restarts after fault conditions.  

This device is commonly used in AC-DC power supplies for appliances, lighting, and industrial applications.
