VIPER17LN Description

Short technical summary and product information.

The VIPER17LN from STMicroelectronics is an integrated circuit designed for AC to DC conversion, specifically functioning as an offline switch for flyback power supplies. This component features an internal switch, simplifying circuit design and reducing component count.

 

Key electrical characteristics include an operating voltage range of 8.5V to 23.5V, a maximum power output of 10W, and an operating frequency of 60kHz. The device supports a duty cycle of up to 70% and offers integrated fault protection, including current limiting, over-temperature, and over-voltage protection.

 

Packaged in an 8-DIP through-hole configuration, the VIPER17LN is suitable for applications requiring isolated power conversion. Its operating temperature range is -40°C to 150°C (TJ), making it robust for various environmental conditions. The component is specified as RoHS3 compliant, with an MSL of 1 and REACH unaffected status, though these compliance details are based on unverified data.

 

This offline switch is ideal for power supply designs where efficiency and reliability are paramount. Its integrated features and through-hole mounting facilitate ease of use in many electronic systems.
