AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix 'W' corresponds to the non-isolated topology and 65kHz frequency variant. Confirm the DIP7K package dimensions match the target PCB layout. Ensure compliance with RoHS3 standards and check that the application does not involve automotive environments, as this standard-grade product is not recommended for such use. Validate component authenticity through authorized channels.

AC DC Converters, Offline Switchers Selection Notes

Select this component for designs requiring a non-isolated flyback or buck topology with integrated switching capabilities. It is suitable for applications needing fixed 65kHz operation and low EMI via frequency hopping. Consider the 650V drain rating and 1.9Ω on-resistance for power handling requirements. Compare against isolated variants like the BM2P101E-Z if galvanic isolation is required instead.
