VIPER20DIP-E

Overview

The VIPER20DIP-E is an offline switcher from the VIPER™ series, designed for flyback converter topologies. It integrates a high-voltage power MOSFET with a current-mode PWM controller. The device supports switching frequencies up to 200 kHz and operates within a supply voltage range of 8V to 15V. Key electrical specifications include a breakdown voltage of 620V and a startup voltage of 11V. It provides fault protection through current limiting and thermal shutdown mechanisms.

Feature Summary

• Integrates a high-voltage power MOSFET with a current-mode PWM controller for compact design
• Supports flyback topology with switching frequencies up to 200 kHz
• Includes built-in fault protection features such as current limiting and thermal shutdown

Applications

• Offline AC-DC converters
• Flyback power supply designs
• General-purpose isolated power sources

Procurement Notes

Verify component status carefully as this specific part number is listed as obsolete or discontinued in available distributor records. Confirm availability through authorized channels or consider alternative active components within the same family if long-term supply is required. Ensure the package type matches the target PCB footprint.

Selection Notes

Select this component for applications requiring a simple, integrated solution for low-to-medium power flyback converters. The internal integration reduces external component count. Verify that the 620V breakdown voltage and 20W power capability align with the specific application requirements before finalizing the design.

Part Context

This device belongs to the VIPER™ series of high-voltage switched-mode power supply ICs. The series is characterized by integrating the power switch and control logic into a single package, simplifying the design of offline converters. The DIP-8 package facilitates through-hole mounting for prototyping or specific industrial applications.

Replacement Considerations

As the part is listed as obsolete, consult STMicroelectronics documentation for direct replacements within the VIPERPlus or VIPER27 families. Verify pin compatibility and electrical ratings when selecting an alternative.
