Description and Introduction

Fixed frequency off line converter The VIPER20ASP-E is a high-voltage converter manufactured by STMicroelectronics. Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 9V to 38V (DC)  
- **Output Power:** Up to 20W (depending on configuration)  
- **Switching Frequency:** 60 kHz (fixed)  
- **Operating Temperature Range:** -40°C to +150°C (junction temperature)  
- **Package:** PowerSO-10  
- **Integrated Power MOSFET:** 800V avalanche-rugged  
- **Primary-Side Regulation (PSR):** Yes  
- **Standby Power Consumption:** <30mW  

### **Descriptions:**  
The VIPER20ASP-E is a monolithic offline switcher IC designed for low-power AC-DC converters. It integrates an 800V power MOSFET, a PWM controller, and protection features, making it suitable for flyback and buck converter topologies.  

### **Features:**  
- **High-Voltage Startup Circuit:** Eliminates the need for an external startup resistor.  
- **Current-Mode Control:** Ensures stable operation under varying load conditions.  
- **Built-in Protections:**  
  - Overvoltage protection (OVP)  
  - Overcurrent protection (OCP)  
  - Thermal shutdown  
  - Short-circuit protection  
- **Soft-Start:** Reduces inrush current.  
- **Frequency Jittering:** Improves EMI performance.  
- **Low Standby Power:** Compliant with energy-saving standards.
