AC DC Converters, Offline Switches STMicroelectronics VIPER28HN Overview
The VIPER28HN from STMicroelectronics is a cutting-edge integrated circuit specifically designed for offline switching applications. As part of the highly regarded VIPER Plus family, this IC offers a robust solution for power supply designs. It operates directly from a rectified mains supply and integrates a PWM controller and a 730V avalanche-rugged power MOSFET. With its high energy efficiency and compact 7-DIP package, the VIPER28HN is ideal for developing cost-effective and space-saving power conversion applications. The integration of multiple functions into a single device not only simplifies the design but also enhances reliability and performance, making it a top choice for bulk purchases by B2B customers looking to innovate or upgrade their power management systems.
VIPER28HN Features
The VIPER28HN integrated circuit boasts several key features that make it highly appealing for a wide range of applications. These include an adjustable switching frequency up to 200 kHz, a very low start-up current of less than 30 µA, and a current mode PWM controller for improved response to load transients. Additionally, its built-in protections such as overload protection, overvoltage protection, and thermal shutdown, safeguard the device and the end application from potential damage, thereby enhancing system reliability and safety.
VIPER28HN Applications
- Power Supplies for Consumer Electronics: Utilized in the manufacture of power supplies for TVs, gaming consoles, and audio equipment, where efficiency and reliability are paramount.
- Small Home Appliances: Perfect for building compact, efficient power sources in household devices such as coffee makers and blenders.
- Smart Lighting Systems: Employs its efficient power conversion capabilities to drive energy-saving LED lighting solutions in both residential and commercial settings.
- Industrial Controls: Offers robust performance in harsh environments typical of industrial applications, ensuring reliability and longevity of control systems.
