VIPER50ASPTR-E

Overview

The VIPER50ASPTR-E is an offline converter from the VIPerPlus family, integrating a PWM controller and a high-voltage vertical power MOSFET. It utilizes VIPower M0 technology to support flyback topologies with up to 200 kHz switching frequency. The device features a 700V breakdown voltage, 1.5A current capability, and operates within an 8V to 15V supply range. It includes internal startup circuitry, soft start, and comprehensive protection mechanisms such as overtemperature and current limiting.

Feature Summary

• Integrates a high-voltage vertical power MOSFET with a state-of-the-art PWM controller on a single silicon chip.
• Supports both primary and secondary regulation loops for flexible offline power supply designs.
• Features automatic burst mode operation in standby condition to minimize no-load power consumption.

Applications

• Offline power supplies requiring wide input voltage ranges
• Adapters and chargers for consumer electronics
• Industrial equipment power systems

Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors. Confirm RoHS3 compliance status and check for obsolete status notifications. Ensure packaging matches the specified PowerSO-10 form factor. Validate datasheet revisions against design requirements before final procurement decisions.

Selection Notes

Select this component for applications requiring integrated high-voltage switching and compact solution size. Consider the 700V drain-source voltage rating for appropriate snubber design. Evaluate thermal performance requirements given the PowerSO-10 package constraints. Verify compatibility with existing control loop compensation networks.

Part Context
