Description and Introduction

Energy Saving VIPer Plus: 6W high voltage converter with direct feedback The VIPER16LD is a monolithic integrated circuit from STMicroelectronics, designed for offline flyback converters. Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 8.5V to 38V (DC)  
- **Output Power:** Up to 16W (depending on topology and conditions)  
- **Switching Frequency:** 60 kHz (fixed)  
- **Operating Temperature Range:** -40°C to +150°C  
- **Drain-Source Voltage (VDS):** 730V (max)  
- **Drain Current (ID):** 0.5A (max)  
- **Standby Power Consumption:** < 30mW  

### **Description:**
The VIPER16LD integrates a PWM controller and a high-voltage power MOSFET, making it suitable for low-power SMPS (Switched-Mode Power Supply) applications. It operates in quasi-resonant mode for improved efficiency and reduced EMI.  

### **Features:**
- **Integrated High-Voltage MOSFET:** 730V avalanche-rugged power section.  
- **Current-Mode PWM Control:** Ensures stable operation.  
- **Soft-Start:** Reduces inrush current.  
- **Frequency Jittering:** Minimizes EMI emissions.  
- **Overvoltage Protection (OVP):** Protects against output surges.  
- **Overcurrent Protection (OCP):** Prevents excessive current draw.  
- **Thermal Shutdown:** Safeguards against overheating.  
- **Auto-Restart Protection:** Recovers automatically after fault conditions.  

The VIPER16LD is commonly used in AC-DC adapters, auxiliary power supplies, and LED drivers.
