Description and Introduction

SMPS PRIMARY I.C. The VIPER20A is a high-voltage converter manufactured by STMicroelectronics. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Manufacturer:** STMicroelectronics (ST)  

### **Specifications:**  
- **Input Voltage Range:** 9V to 38V (DC)  
- **Output Power:** Up to 20W  
- **Switching Frequency:** 60 kHz (fixed)  
- **Operating Temperature Range:** -40°C to +150°C (junction temperature)  
- **Package:** SO-16 (Surface Mount)  
- **Integrated Features:**  
  - High-voltage startup circuit  
  - PWM controller with fixed frequency  
  - Overvoltage protection (OVP)  
  - Overcurrent protection (OCP)  
  - Thermal shutdown  
  - Soft-start function  

### **Descriptions:**  
The VIPER20A is a monolithic high-voltage power converter IC designed for offline and DC-DC applications. It integrates a PWM controller, a high-voltage power MOSFET, and protection features, making it suitable for compact and efficient power supply designs.  

### **Features:**  
- **High-Voltage Startup:** Eliminates the need for an external startup resistor.  
- **PWM Control:** Fixed-frequency operation for stable performance.  
- **Protection Mechanisms:** Includes OVP, OCP, and thermal shutdown for reliability.  
- **Low Standby Power Consumption:** Optimized for energy-efficient applications.  
- **Soft-Start:** Reduces inrush current during startup.  

This information is based solely on the manufacturer's datasheet and technical documentation.
