VIPER53ESPTR-E

Overview

The VIPER53ESPTR-E is an offline switcher from the VIPer™ series, manufactured by STMicroelectronics. It integrates a high voltage MDMesh Power MOSFET with an enhanced current mode PWM controller in a single package. The device operates with a switching frequency up to 300kHz and supports flyback topology. It features a breakdown voltage of 620V and is housed in a PowerSO-10 surface mount package. The component provides power capabilities up to 40W in wide range input voltage applications.

Feature Summary

• Integrates high voltage MDMesh Power MOSFET with current mode PWM controller
• Includes automatic burst mode for efficient standby operation
• Features overload and short-circuit control via feedback monitoring

Applications

• Offline power supplies with secondary power capability up to 40W
• Wide range input voltage AC/DC converters
• Auxiliary power supply circuits

Procurement Notes

Verify the specific suffix 'SPTR' indicates the PowerSO-10 surface mount packaging configuration distinct from DIP variants. Confirm active status as some sources indicate this specific part number may be obsolete or discontinued compared to the standard DIP versions. Ensure compatibility with automated pick-and-place equipment due to the SMD form factor.

Selection Notes

Select this variant when surface mount assembly is required for the VIPER53 functionality. The PowerSO-10 package offers thermal performance suitable for 40W wide-range applications. Compare against the DIP-8 version if through-hole mounting is preferred for higher power density up to 50W in single European voltage ranges.

Part Context

This component belongs to the VIPer53-E family of fixed frequency offline converters. It shares core controller architecture with the VIPER53E but differs in physical packaging. The family is designed for cost-effective, high-reliability power solutions compliant with European directives regarding standby power consumption.
