VIPER53EDIP-E

Overview

The VIPER53EDIP-E is an offline switch integrating a high voltage MDMesh power MOSFET and an enhanced current mode PWM controller in an 8-DIP package. It supports flyback topology with a maximum switching frequency of 300 kHz and a breakdown voltage of 620 V. The device provides up to 50 W output power in single European voltage ranges or 30 W in wide input ranges. Operating parameters include a supply voltage range of 8.4 V to 19 V, a start-up voltage of 11.5 V, and a junction temperature range of -40°C to 150°C.

Feature Summary

• Integrates high voltage MDMesh power MOSFET with enhanced current mode PWM controller
• Features automatic burst mode for efficient standby operation compliant with Blue Angel standards
• Includes overload and short-circuit control managed by feedback monitoring with delayed reset
• Provides primary regulation protection via high gain error amplifier against secondary loop failure

Applications

• Offline power supplies with secondary power capability up to 30W in wide range input voltage
• Offline power supplies with secondary power capability up to 50W in single European voltage range
• Auxiliary power supply circuits

Procurement Notes

Verify the specific suffix 'EDIP' confirms the 8-DIP through-hole package variant. Confirm the manufacturer is STMicroelectronics. Check the datasheet for the latest revision date to ensure compatibility with design requirements. Validate that the component status is active for long-term production planning.

Selection Notes

Select this component for designs requiring integrated high-voltage switching in a DIP package. It is suitable for applications needing primary side regulation with robust fault protection. Consider the 300 kHz maximum frequency for transformer size optimization. Ensure the thermal management supports the specified junction temperature limits.

Part Context

This part belongs to the VIPer53-E series of fixed frequency offline converters from STMicroelectronics. The series combines power and control functions to simplify AC-DC converter designs. The VIPer53EDIP-E specifically denotes the DIP-8 package version, distinguishing it from surface mount variants like the ESP package.
