VIPER265KDTR Description

Short technical summary and product information.

The VIPER265KDTR from STMicroelectronics is an integrated circuit designed for AC/DC conversion applications, functioning as an offline switch. It supports multiple topologies including Buck, Buck-Boost, and Flyback, providing flexibility in power supply design.

 

This device features an input voltage range of 11.5V to 23.5V and can deliver up to 20W of power. It operates efficiently with a duty cycle of 80% and a frequency of 60kHz. The IC includes essential control features like EN and Soft Start, along with fault protection mechanisms such as current limiting, overload protection, and short circuit protection.

 

Designed for surface mounting, the VIPER265KDTR comes in a 16-SOIC package with specific dimensions of 0.154" width. Its operating temperature range spans from -40°C to 150°C (TJ), making it suitable for various environmental conditions. The internal switch capability simplifies circuit design, and the output isolation can be configured as either isolated or non-isolated.
