The STMicroelectronics VIPER™ VIPER50-E is a high-performance offline flyback converter IC designed for power supply applications. This component integrates a high-voltage power MOSFET and a PWM controller, enabling efficient operation up to 200kHz switching frequency. Key control features include frequency control, soft-start, and synchronization capabilities. Built-in fault protection mechanisms provide robust operation through current limiting and over-temperature shutdown. The VIPER50-E supports up to 50W output power and features a 620V breakdown voltage, making it suitable for isolated power supplies in industrial, lighting, and consumer electronics sectors. It is packaged in a 5-PENTAWATT HV (bent and staggered leads) for surface mounting and supplied in tubes. Operating voltage range is 8V to 15V with an 11V start-up voltage.
