Procurement Notes

Verify the exact package type (e.g., Pentawatt) and pinout configuration against the official STMicroelectronics datasheet before integration. Ensure thermal management requirements are met for the specific application environment. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component for applications requiring integrated high-voltage MOSFETs and PWM control in a compact form factor. Consider the 700V rating and 60 kHz switching frequency when designing transformer specifications. Evaluate the 7 W power limit against your load requirements. Check the DIP-8 or Pentawatt package availability depending on your PCB layout constraints and thermal dissipation needs.

Part Context

This part belongs to the VIPer50 family of offline switchers. It combines power and control functions to reduce external component count. The VIPer50 series is designed for cost-effective, high-reliability power solutions. It simplifies design by integrating critical elements like the startup circuit and high-voltage transistor.

Replacement Considerations

Check for direct substitutes within the VIPer50 family, such as VIPer50A-22-E variants with different packaging. Verify electrical compatibility including voltage ratings and current capabilities. Ensure pin-to-pin compatibility if replacing in existing designs.
