Procurement Notes

Verify component authenticity as the IR1150STRPBF is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers. Ensure the received units match the original Infineon specifications and packaging standards. Check for any end-of-life notifications or discontinuance alerts prior to procurement to mitigate supply chain risks.

Selection Notes

Select this component for designs requiring robust CCM PFC control with one-cycle regulation. Consider the 8-SOIC package constraints and thermal requirements for the intended application. Evaluate compatibility with external MOSFETs and passive components. Assess if the fixed 200kHz switching frequency aligns with electromagnetic interference (EMI) constraints and system performance goals.
