VIPER115XSTR Description

Short technical summary and product information.

The VIPER115XSTR from STMicroelectronics is an integrated circuit designed for offline AC/DC conversion applications. This device operates within a supply voltage range of 4.5V to 30V and boasts a high breakdown voltage of 800V.

 

Key electrical specifications include a maximum duty cycle of 80% and a switching frequency of 30kHz, enabling efficient power conversion up to 12W. The converter supports multiple topologies, including Buck, Buck-Boost, and Flyback, and features essential fault protection mechanisms such as current limiting, overload, overvoltage, and short circuit protection. It also includes a soft-start control feature for smoother power-up sequences.

 

Packaged in a 10-SSOP, the VIPER115XSTR is designed for surface mount applications. The operating temperature range is -40°C to 125°C (TJ), making it suitable for various environmental conditions. This non-isolated converter integrates the switching element internally, simplifying circuit design.
