Description and Introduction

VIPer Plus family: fixed frequancy high performance off line high voltage converter The VIPER17LDTR is a high-voltage converter manufactured by STMicroelectronics. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
STMicroelectronics  

### **Specifications:**  
- **Input Voltage Range:** 8.5V to 38V  
- **Output Power:** Up to 17W (depending on configuration)  
- **Switching Frequency:** 60 kHz (fixed)  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package:** SO-8 (Surface Mount)  
- **Integrated Features:**  
  - High-voltage startup circuit  
  - PWM controller  
  - Overvoltage protection (OVP)  
  - Overcurrent protection (OCP)  
  - Thermal shutdown  

### **Descriptions:**  
- The VIPER17LDTR is a monolithic switch-mode power supply (SMPS) controller with an integrated 800V avalanche-rugged power MOSFET.  
- Designed for offline and DC-DC converter applications, it simplifies the design of flyback and buck converters.  
- Includes a built-in high-voltage startup circuit, eliminating the need for an external startup resistor.  

### **Features:**  
- **High Integration:** Combines PWM controller and power MOSFET in a single chip.  
- **Low Standby Power:** Optimized for energy-efficient applications.  
- **Protection Mechanisms:**  
  - Auto-restart for overvoltage, overcurrent, and overtemperature conditions.  
  - Frequency jittering for improved EMI performance.  
- **Soft-start:** Reduces inrush current during startup.  

For detailed application notes and schematics, refer to the official STMicroelectronics datasheet.
