VIPER50SP13TR

Overview

The VIPER50SP13TR is a high-voltage integrated circuit for offline flyback power supplies, part of the VIPER™ family. It combines a 700V power MOSFET with a PWM controller in a single chip. The device supports switching frequencies up to 200kHz and delivers up to 50W of output power. Key electrical parameters include a supply voltage range of 8V to 15V, a breakdown voltage of 620V, and a startup voltage of 11V. It utilizes a PowerSO-10 package with an exposed bottom pad for thermal management.

Feature Summary

• Integrates a high-voltage vertical power MOSFET with advanced PWM control circuitry on a single silicon chip.
• Features current mode control with adjustable switching frequency and soft-start capability.
• Includes comprehensive protection mechanisms such as over-temperature shutdown and programmable current limiting.

Applications

• Offline power supplies requiring up to 50W output
• Battery chargers for consumer electronics
• Adapters and auxiliary power supplies

Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm the specific ordering suffix matches the required tape-and-reel packaging configuration. Check for obsolescence status and lead times due to potential lifecycle changes. Ensure compliance with relevant environmental directives applicable to your region before finalizing procurement orders.

Selection Notes

Select this component for designs requiring a compact, high-voltage solution for low-to-medium power applications. Consider the PowerSO-10 package for adequate thermal dissipation at higher power levels. Evaluate the need for external components for frequency adjustment versus fixed-frequency operation. Compare against newer generations like VIPERGAN for improved efficiency requirements.

Part Context

The VIPER50SP13TR belongs to the VIPER™ series of high-voltage power switches. This series is designed to simplify power supply design by integrating control and power stages. It replaces discrete solutions, reducing component count and board space. The SP13 suffix indicates the specific reel packaging format used for automated assembly processes.

Replacement Considerations

Check for direct replacements within the VIPER50 series or upgraded variants like VIPER50A. Consult official substitution guides for pin-compatible alternatives. Verify that any substitute maintains the required voltage ratings and power capabilities for the specific application.
