Description and Introduction

VIPer Plus family: fixed frequancy high performance off line high voltage converter The VIPER17HD is a monolithic power converter IC manufactured by STMicroelectronics. Below are the factual details from Ic-phoenix technical data files:

### **Manufacturer:**  
STMicroelectronics  

### **Specifications:**  
- **Input Voltage Range:** 8.5V to 38V (DC)  
- **Output Power:** Up to 17W (in flyback topology)  
- **Switching Frequency:** Fixed 60 kHz  
- **Integrated Power MOSFET:** 800V avalanche-rugged  
- **Current Mode PWM Control**  
- **Protection Features:**  
  - Overvoltage protection (OVP)  
  - Overload protection (OLP)  
  - Short-circuit protection (SCP)  
  - Thermal shutdown  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package:** SO-16 or PowerSO-10  

### **Descriptions:**  
The VIPER17HD is a high-voltage converter IC designed for offline power supplies. It integrates an 800V power MOSFET, PWM controller, and protection features, making it suitable for cost-effective, compact power supply designs.  

### **Features:**  
- **High-Voltage Startup:** Internal high-voltage startup circuit eliminates the need for an external bias winding.  
- **Low Standby Power Consumption:** < 100mW at 230V AC input.  
- **Soft Start:** Reduces inrush current during startup.  
- **Frequency Jittering:** Reduces EMI emissions.  
- **Adjustable Output Voltage:** Via external feedback network.  

This information is strictly based on STMicroelectronics' datasheet and technical documentation.
