VIPER17HDTR

Overview

The VIPER17HDTR is an offline switch from the VIPerPlus series, designed for flyback topology applications. It integrates a high-voltage power section with a breakdown voltage of 800V and operates at a fixed switching frequency of 115kHz. The device supports a maximum output power of 10W and features a startup voltage range of 8.5V to 23.5V. It includes built-in protections such as current limiting, overtemperature shutdown, and overvoltage protection. The component is housed in a 16-SOIC package.

Feature Summary

• Integrates an 800V rugged power section with PWM control for high-voltage offline conversion.
• Features advanced frequency jittering to reduce electromagnetic interference filter costs.
• Includes safe auto-restart capability following fault condition removal.

Applications

• Standby power supplies for consumer electronics
• Battery chargers for mobile devices
• General-purpose isolated AC-DC converters

Procurement Notes

Verify the specific suffix 'H' indicates the 115kHz operating frequency variant when sourcing replacements. Confirm that the 'TR' suffix corresponds to the required reel packaging format for automated assembly processes. Ensure compatibility with the 16-SOIC footprint during procurement planning.

Selection Notes

Select this model for designs requiring a fixed 115kHz switching frequency within the VIPerPlus family. It is suitable for applications needing integrated high-voltage startup and robust fault protection mechanisms without external discrete components.

Part Context

This component belongs to the VIPerPlus series of high-voltage power switches. It is part of a broader family including variants like VIPER17LDTR, which differs primarily in its switching frequency specification. The series targets cost-effective, compact power supply solutions.

Replacement Considerations

VIPER17LDTR is documented as a parameter-equivalent alternative within the same product line.
