AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix 'RA' against the official Navitas Semiconductor datasheet to confirm packaging and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your region. Cross-reference the Mouser number 740-NV9581F2C2-RA or equivalent distributor codes to validate authenticity and current availability status before finalizing procurement orders.

AC DC Converters, Offline Switchers Selection Notes

Select this component when a monolithic solution combining a 700V GaN FET and its gate driver is required. The 210mΩ on-resistance offers a balance between conduction losses and cost. Consider the 164kHz/225kHz frequency options for EMI management. The wide supply voltage range allows flexibility in auxiliary power design. Ensure thermal management strategies align with the QFN-23 package capabilities.

AC DC Converters, Offline Switchers Part Context

This part belongs to the GaNSense Control family, which integrates power switches and controllers into a single chip. Navitas Semiconductor specializes in Gallium Nitride (GaN) power ICs that replace traditional silicon MOSFETs and discrete drivers. This integration reduces component count, board space, and improves overall system efficiency compared to discrete solutions.

AC DC Converters, Offline Switchers Replacement Considerations

Check for direct substitutes within the NV9581 series with different Rds(on) values if current handling needs vary. Verify pin-to-pin compatibility with alternative GaN ICs from other manufacturers only if electrical parameters match exactly.
