The STMicroelectronics VIPER™ VIPER50-22-E is an offline flyback converter IC designed for high-efficiency power supply applications up to 50W. This component integrates a high-voltage power MOSFET and a PWM controller, enabling compact and cost-effective designs. Key features include a switching frequency up to 200kHz, facilitating smaller magnetic components, and a built-in startup circuit operating at 11V.
The VIPER50-22-E offers robust fault protection mechanisms, including current limiting and over-temperature shutdown, ensuring operational reliability. Control features such as frequency control and soft-start contribute to smooth power delivery and reduced inrush current. Its 620V breakdown voltage is suitable for mains operation. This device is commonly utilized in consumer electronics, industrial automation, and lighting applications requiring isolated power conversion. The component is supplied in a 5-PENTAWATT package for surface mounting.
