Description and Introduction

LOW POWER OFF LINE SMPS PRIMARY SWITCHER The VIPER12ADIP is a low-power offline switched-mode power supply (SMPS) primary switcher manufactured by STMicroelectronics.  

### **Specifications:**  
- **Input Voltage Range:** 9V to 38V (DC)  
- **Output Power:** Up to 12W (depending on configuration)  
- **Switching Frequency:** 60 kHz (fixed)  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package:** DIP-8 (through-hole)  
- **Integrated Features:**  
  - High-voltage startup circuit  
  - PWM controller with current mode control  
  - Built-in overvoltage protection (OVP)  
  - Thermal shutdown protection  
  - Short-circuit protection  

### **Description:**  
The VIPER12ADIP is a monolithic IC designed for offline power supplies, combining a PWM controller and a high-voltage power MOSFET. It is suitable for low-power applications such as auxiliary power supplies, home appliances, and industrial controls.  

### **Features:**  
- **Low Standby Power:** Optimized for energy-efficient designs.  
- **Auto-Restart Protection:** Recovers automatically after fault conditions.  
- **Current Limiting:** Ensures safe operation under overload.  
- **Soft-Start:** Reduces inrush current during startup.  

For detailed electrical characteristics, refer to the official STMicroelectronics datasheet.

Description and Introduction

LOW POWER OFF LINE SMPS PRIMARY SWITCHER The VIPER12ADIP is a monolithic IC from STMicroelectronics (STM) designed for offline SMPS (Switched-Mode Power Supply) applications. Below are its key specifications, descriptions, and features:  

### **Manufacturer:**  
- **STM (STMicroelectronics)**  

### **Specifications:**  
- **Input Voltage Range:** 9V to 38V (DC)  
- **Output Power:** Up to 8W (depending on topology and cooling)  
- **Switching Frequency:** 60 kHz (fixed)  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package:** DIP-8 (Dual In-line Package)  
- **Drain-Source Voltage (VDSS):** 730V  
- **Peak Drain Current:** 0.5A  
- **Standby Power Consumption:** <1W (at 230V AC)  
- **Integrated Features:**  
  - PWM controller  
  - High-voltage startup circuit  
  - Current-mode control  
  - Overvoltage protection (OVP)  
  - Overload protection (OLP)  
  - Thermal shutdown  

### **Descriptions:**  
- The VIPER12ADIP is a low-power offline converter IC combining a PWM controller and a high-voltage power MOSFET.  
- It is optimized for cost-effective, low-power SMPS designs, such as chargers, adapters, and auxiliary power supplies.  
- The built-in high-voltage startup eliminates the need for an external startup resistor.  

### **Features:**  
- **High-Voltage Startup:** Integrated startup cell reduces external components.  
- **Current-Mode Control:** Ensures stable operation and fast transient response.  
- **Protections:** Includes OVP, OLP, thermal shutdown, and soft-start.  
- **Low Standby Power:** Compliant with energy-saving standards.  
- **Fixed Frequency Operation:** Reduces EMI filtering complexity.  

This information is strictly based on STM's official datasheet for the VIPER12ADIP.
