VIPER53SP

Overview

The VIPER53SP is a surface-mount AC-DC converter from STMicroelectronics, housed in a 10-pin PowerSO package. It integrates an enhanced current mode PWM controller with a high-voltage MDmesh power MOSFET. The device supports a maximum switching frequency of 300 kHz and operates within an input voltage range of 85 VAC to 265 VAC. It delivers up to 65 W output power in single European voltage ranges or 40 W in wide-range inputs. Key electrical parameters include a breakdown voltage of 620 V, a supply current of 9 mA, and a maximum operating temperature of 125 °C.

Feature Summary

• Integrates an enhanced current mode PWM controller with a high-voltage MDmesh power MOSFET for compact design.
• Features automatic burst mode operation in standby conditions to meet strict energy efficiency standards.
• Includes comprehensive protection mechanisms such as overvoltage, over-temperature, and overload control.

Applications

• Offline power supplies for set-top boxes
• Power adapters for DVD players and video recorders
• Auxiliary power supplies for televisions and PCs

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and compliance status. Ensure the component matches the required thermal and electrical specifications for the target application. Cross-reference ordering information with authorized distributors to avoid counterfeit parts. Confirm lead times and availability directly with suppliers before finalizing procurement plans.

Selection Notes

Select this component for applications requiring high integration and low standby power consumption. The DIP-8 variant suits through-hole designs, while the PowerSO-10 version is ideal for surface-mount assembly. Consider the 65 W capability for single voltage ranges when sizing the power supply. Evaluate the need for secondary regulation if higher precision is required beyond primary side control.

Part Context

The VIPer53 belongs to the VIPower family of intelligent power switches developed by STMicroelectronics. This series combines control logic and power processing in a single package to reduce system complexity. The VIPer53 specifically targets cost-effective offline power conversion solutions for consumer electronics and auxiliary power needs.
