VIPER38LDTR Description

Short technical summary and product information.

The STMicroelectronics VIPER38LDTR is an integrated circuit designed for offline switching applications, specifically utilizing a flyback topology. This device is suitable for power supplies requiring up to 20W of output power.

 

Key electrical characteristics include an operating voltage range of 8.5V to 23.5V and a switching frequency of 60kHz. It features an 80% duty cycle and includes comprehensive fault protection, such as current limiting, over temperature, over voltage, and short circuit protection. The internal switch simplifies design, and the output is isolated.

 

Packaged in a 16-SOIC (0.154", 3.90mm Width) surface mount configuration, the VIPER38LDTR operates within a temperature range of -40°C to 150°C (TJ). Its RoHS3 compliance indicates adherence to environmental standards, though this status is unverified.

 

This component is well-suited for various AC/DC conversion applications where a compact and efficient offline switching solution is needed.
