VIPER06XS

AC DC Converters, Offline Switchers Overview

The VIPER06XS is an offline AC/DC converter from the VIPerPlus family, designed for non-isolated buck and flyback topologies. It integrates an 800 V avalanche rugged power section with a PWM controller operating at a fixed frequency of 30 kHz. The device features frequency jittering to reduce electromagnetic interference (EMI). Key electrical parameters include a maximum duty cycle of 80%, a typical standby power consumption below 30 mW at 265 VAC, and a quiescent supply current of 1.3 mA. It supports universal input mains ranges and includes built-in protections such as thermal shutdown with hysteresis, delayed overload protection, and open-loop failure detection.

AC DC Converters, Offline Switchers Feature Summary

• Provides safe auto-restart functionality following fault conditions including overload or overheating
• Eliminates the need for auxiliary windings in low-power configurations through self-powering capability

AC DC Converters, Offline Switchers Applications

• Non-isolated switched-mode power supplies
• Direct feedback AC/DC conversion circuits
• Low-power adapter designs requiring minimal external components

AC DC Converters, Offline Switchers Procurement Notes

Verify the specific package variant, as the VIPER06XS is available in SSO-10 and SSOP-10 configurations. Confirm that the selected part matches the required thermal and mechanical specifications for your printed circuit board layout. Ensure compliance with RoHS standards if applicable to your manufacturing region. Cross-reference the datasheet revision to confirm pinout consistency before finalizing procurement orders.

AC DC Converters, Offline Switchers Selection Notes

Select this component for designs utilizing buck or flyback topologies where an 800 V breakdown voltage is necessary. The fixed 30 kHz switching frequency aids in filtering design compared to higher-frequency alternatives. Consider the adjustable current limit feature for custom protection thresholds. Evaluate the thermal performance requirements given the integrated power section and ensure adequate heat dissipation paths are included in the system architecture.

AC DC Converters, Offline Switchers Part Context

This device belongs to the VIPerPlus series, which focuses on energy-saving solutions for offline converters. It complements other variants like the VIPER06HN (115 kHz) and VIPER06LX (60 kHz) by offering a lower switching frequency option. The series emphasizes reduced standby power and simplified implementation by integrating control logic directly with the high-voltage power switch.

AC DC Converters, Offline Switchers Replacement Considerations

The VIPER06HN serves as a functional alternative within the same family, offering identical topology support but operating at a fixed 115 kHz frequency. Designers must account for differences in switching speed and associated EMI characteristics when substituting between these models.
