VIPER20ASPTR-E

Overview

The VIPER20ASPTR-E is an offline flyback converter from the VIPerPlus family, manufactured by STMicroelectronics. It integrates a high-voltage power MOSFET with a fixed-frequency PWM controller in a single PowerSO-10 package. The device supports a maximum switching frequency of 200 kHz and operates within a supply voltage range of 8 V to 15 V. It features a 700 V breakdown voltage for the internal switch and includes built-in fault protection mechanisms such as current limiting and thermal shutdown.

Feature Summary

• Integrates a high-voltage power MOSFET with a fixed-frequency PWM controller for compact design
• Includes built-in fault protection mechanisms such as current limiting and thermal shutdown
• Supports flyback topology with burst mode operation for low standby consumption

Applications

• Adapters and chargers for consumer electronics
• General-purpose isolated DC/DC converters
• Battery chargers for portable devices

Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS3 compliance and MSL rating prior to assembly. Check for alternative sources or equivalent replacements as this specific part number is no longer actively produced by the manufacturer.

Selection Notes

Select this component for applications requiring a simple, cost-effective offline solution with integrated high-voltage switching. Ensure the design accommodates the fixed 200 kHz switching frequency and the specific PowerSO-10 thermal requirements. Verify that the 700 V drain-source voltage rating meets the input voltage stress conditions of the target application.

Part Context

This part belongs to the VIPerPlus family of high-voltage offline converters. It shares architectural similarities with other members like the VIPER25 but differs in switching frequency and specific protection thresholds. The family is designed to minimize external component count while meeting energy efficiency standards.
