Description and Introduction

LOW POWER OFF LINE SMPS PRIMARY SWITCHER The VIPer12AS is a low-power offline converter IC manufactured by STMicroelectronics. Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 9V to 38V (DC)  
- **Output Power:** Up to 8W (depending on topology)  
- **Switching Frequency:** 60 kHz (fixed)  
- **Drain-Source Voltage (VDS):** 730V (max)  
- **Drain Current (ID):** 0.3A (max)  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package:** SO-8 (Surface Mount)  

### **Descriptions:**  
The VIPer12AS is a monolithic power IC designed for offline SMPS (Switched-Mode Power Supply) applications. It integrates a high-voltage power MOSFET with a PWM controller, making it suitable for low-power AC-DC converters. It operates in current-mode control for improved regulation and protection.  

### **Features:**  
- **Integrated High-Voltage MOSFET:** 730V breakdown voltage.  
- **Current-Mode PWM Control:** Ensures stable operation.  
- **Built-in Soft-Start:** Reduces inrush current.  
- **Protection Features:**  
  - Overvoltage protection (OVP)  
  - Overload protection (OLP)  
  - Thermal shutdown  
  - Undervoltage lockout (UVLO)  
- **Low Standby Power Consumption:** Suitable for energy-efficient designs.  
- **Fixed Switching Frequency:** 60 kHz for simplified design.  

This information is based on the manufacturer's datasheet. For detailed application notes, refer to STMicroelectronics' official documentation.
