VIPER37HDTR Description

Short technical summary and product information.

The STMicroelectronics VIPER37HDTR is an integrated circuit designed for AC/DC conversion applications. This offline switcher utilizes a flyback topology and includes an internal switch.

 

Key electrical specifications include a breakdown voltage of 800V, a supply voltage range of 8.5V to 23.5V, and a startup voltage of 14V. It offers a power output of 20W with a duty cycle of 80% and a switching frequency of 115kHz. The device incorporates fault protection for current limiting, over-temperature, and over-voltage conditions.

 

Packaged in a 16-SOIC surface-mount configuration, the VIPER37HDTR operates across a wide temperature range from -40°C to 150°C (TJ). Its isolated output design makes it suitable for various power supply applications requiring efficient and reliable AC/DC conversion.

 

Environmental compliance includes RoHS3 compliance and a Moisture Sensitivity Level (MSL) of 1. The REACH status is unaffected.
