Description and Introduction

VIPerPlus family: fixed frequency high performance off line high voltage converter The VIPER27HD 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:** 8V to 38V (DC)  
- **Output Power:** Up to 18W (depending on configuration)  
- **Switching Frequency:** 60 kHz (fixed)  
- **Integrated Power MOSFET:** 800V avalanche-rugged  
- **Standby Power Consumption:** < 30mW  
- **Operating Temperature Range:** -40°C to +150°C (junction temperature)  
- **Protection Features:**  
  - Overvoltage protection (OVP)  
  - Overload protection (OLP)  
  - Short-circuit protection (SCP)  
  - Thermal shutdown  

### **Description:**  
The VIPER27HD is a monolithic offline converter IC designed for low-power SMPS (Switched-Mode Power Supply) applications. It integrates an 800V power MOSFET, PWM controller, and protection circuits, making it suitable for cost-effective and compact power supply designs.  

### **Features:**  
- **High-Voltage Startup Circuit:** Eliminates the need for an external startup resistor.  
- **Current-Mode Control:** Ensures stable operation under varying load conditions.  
- **Soft-Start:** Reduces inrush current during startup.  
- **Adjustable Output Voltage:** Via external feedback components.  
- **Low EMI Emissions:** Compliant with industry standards.  
- **Package Options:** SO-16 or PowerSO-10.  

This information is strictly factual and based on the manufacturer's datasheet.
