Overview

The VIPER06XSTR is a high-voltage offline power converter from the VIPerPlus family, designed for buck or flyback topologies with an 800V breakdown voltage. It integrates a PWM controller with an 800V avalanche-rugged power MOSFET, enabling compact 8W power supplies for appliances and smart home automation.

Why Choose This Part

This device eliminates the need for an auxiliary winding in low-power designs, significantly reducing transformer complexity and BOM cost. It features frequency jittering to reduce EMI and includes comprehensive fault protection including hysteretic thermal shutdown and current limiting with an adjustable set point.

Applications

Non-isolated Buck Converters
Ideal for low-power consumer appliances where a simple buck topology is used to provide logic voltage directly from AC mains.
Home Automation Nodes
Provides efficient standby power for IoT sensors and smart switches with a low 60uA quiescent current.
Small Household Appliances
Used in coffee machines or microwave ovens where a reliable, low-component-count offline power supply is required.
Auxiliary Power Supplies
Serves as a secondary standby supply for larger industrial systems or white goods.
