VIPER06HS

AC DC Converters, Offline Switchers Overview

The VIPER06HS is an offline high-voltage converter from the VIPerPlus family, integrating a PWM controller and an 800 V avalanche-rugged power MOSFET in a single package. It operates at a fixed frequency of 115 kHz with frequency jittering to reduce electromagnetic interference. The device supports non-isolated flyback topologies, offering universal input voltage range from 90 V to 265 V AC. It provides a continuous output of 12 V at 0.35 A, achieving average efficiency greater than 74% and standby consumption below 30 mW at 230 V AC.

AC DC Converters, Offline Switchers Feature Summary

• Integrates an 800 V avalanche-rugged power section with a low-voltage PWM controller chip in one package.
• Features PWM operation at 115 kHz with frequency jittering for lower electromagnetic interference.
• Includes onboard soft-start, current limiting with adjustable set point, and safe auto-restart after fault conditions.
• Provides comprehensive protection against thermal shutdown with hysteresis, delayed overload, and open loop failure.

AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix (e.g., HSTR) for packaging type when ordering. Confirm RoHS compliance status through official documentation. Ensure the application design matches the non-isolated flyback topology constraints. Check for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement.

AC DC Converters, Offline Switchers Selection Notes

Select this component for designs requiring high voltage integration and low standby power. It is suitable for applications needing robust avalanche ruggedness and EMI reduction via jittering. Consider the fixed 115 kHz switching frequency for filter design. Evaluate the need for adjustable current limiting and thermal protection features inherent to the device.
