Procurement Notes

Verify the specific suffix '22' against official STMicroelectronics documentation to confirm pinout and functional compatibility, as variations exist within the VIPER50 family. Ensure the Pentawatt package type matches your PCB footprint requirements. Cross-reference the datasheet revision date to guarantee alignment with current manufacturing specifications and RoHS compliance status before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high integration and reliability in low-to-medium power offline converters. The integrated high-voltage MOSFET simplifies design by reducing external component count. Consider the 200 kHz switching frequency for transformer size optimization. Evaluate thermal performance requirements given the Pentawatt package's power dissipation capabilities relative to the expected load conditions.

Part Context

The VIPER50 series represents STMicroelectronics' VIPower M0 technology, designed for cost-effective and compact offline power solutions. This family combines advanced control logic with high-voltage power processing. The VIPER50-22-E specifically targets applications needing robust protection and high efficiency in a compact form factor, serving as a key solution for modern energy-efficient power adapters.

Replacement Considerations

Direct substitutes include other variants within the VIPER50 family, such as VIPER50-E or VIPER50A-E, provided the pinout and electrical characteristics align with the specific '22' configuration. Verify that alternative packages maintain equivalent thermal and electrical performance for the target application.
