VIPER53SP-E

Overview

The VIPER53SP-E is a high-voltage AC/DC converter integrating an enhanced current mode PWM controller and an MDMesh power MOSFET in a PowerSO-10 package. It supports flyback topology with a switching frequency up to 300 kHz and a breakdown voltage of 620 V. The device delivers up to 65 W output power, operates on a supply voltage range of 9.3 V to 17 V, and consumes 9 mA during operation.

Feature Summary

• Integrates high-voltage MDMesh power MOSFET with current mode PWM controller
• Includes high-voltage start-up current source for simplified design
• Features automatic burst mode for efficient standby conditions
• Provides comprehensive protection against overload, short circuit, and overtemperature

Applications

• Offline power supplies requiring secondary regulation
• Industrial equipment power systems
• Motor drive power circuits

Procurement Notes

Verify the specific suffix 'SP' indicates the PowerSO-10 surface mount package variant distinct from DIP versions. Confirm RoHS compliance status and check for any recent product change notices regarding packaging or pinout modifications before finalizing procurement specifications.

Selection Notes

Select this component when a surface-mount solution is required for offline converters needing up to 65 W capability. The extended VDD voltage range offers transformer design flexibility compared to standard variants. Ensure thermal management aligns with the 150°C maximum junction temperature rating for the target application environment.

Part Context

This part belongs to the VIPER53-E family of smart high-voltage switches designed for offline power supplies. It combines control logic and power switching in a single integrated circuit, eliminating the need for external bias windings or complex startup circuits typically found in discrete solutions.

Replacement Considerations

The VIPER53EDIP-E serves as a direct functional alternative if through-hole DIP-8 packaging is preferred instead of the PowerSO-10 surface mount format.
