VIPER06XSTR

AC DC Converters, Offline Switchers Overview

The VIPER06XSTR is an offline AC-DC converter from the VIPerPlus family, integrating a PWM controller and an 800 V avalanche-rugged power MOSFET in an SSOP-10 package. It operates at a fixed switching frequency of 30 kHz with frequency jittering for EMI reduction. The device supports Buck and Flyback topologies, delivering up to 8 W output power. Key electrical parameters include a minimum input voltage of 11.5 V, maximum of 23.5 V, and a maximum duty cycle of 80%. Quiescent current is 1.3 mA, enabling standby consumption below 30 mW. It functions within a temperature range of -40°C to 150°C.

AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix 'XS' against the official STMicroelectronics datasheet to confirm pinout compatibility and electrical characteristics. Ensure the SSOP-10 package dimensions match the target PCB footprint. Confirm RoHS compliance status and check for any recent lifecycle notices or obsolescence warnings directly from the manufacturer before finalizing procurement.

AC DC Converters, Offline Switchers Selection Notes

Select this component for designs requiring high voltage tolerance and integrated power switching in a compact form factor. The 30 kHz frequency is suitable for cost-sensitive applications where moderate efficiency is acceptable. Consider the 8 W power limit and 800 V breakdown voltage when designing for universal mains inputs. Evaluate the need for external components versus the internal protections offered.

AC DC Converters, Offline Switchers Part Context

This part belongs to the VIPerPlus family of energy-saving high-voltage converters by STMicroelectronics. The family includes variants with different switching frequencies, such as 60 kHz and 115 kHz options. These devices are designed to minimize external component count by integrating startup circuits and error amplifiers, facilitating efficient power supply development.

AC DC Converters, Offline Switchers Replacement Considerations

Check for direct substitutes within the VIPerPlus family, such as VIPER06L or VIPER06H, which offer different switching frequencies. Verify that alternative parts maintain the same SSOP-10 package and 800 V rating. Cross-reference pinouts and thermal performance specifications to ensure mechanical and electrical compatibility.
