Procurement Notes
Verify the specific suffix DR2 against the official onsemi datasheet to confirm package type and tape/reel specifications. Confirm RoHS compliance status through current manufacturer documentation. Ensure the part number matches the exact ordering code required for your bill of materials, as variations may exist in packaging or revision levels.
Selection Notes
Select this component when designing synchronous buck converters requiring integrated high and low-side drive capabilities. It is suitable for applications needing moderate drive strength with fast switching speeds. Consider the SOIC-8 package constraints and thermal requirements during PCB layout. Verify input signal compatibility with the controller IC used in the design.
Part Context
The NCP5355 belongs to onsemi's portfolio of power management integrated circuits, specifically within the gate driver category. This series targets efficient power conversion solutions. The DR2 designation indicates a specific surface-mount package variant. It is part of a broader family of drivers designed for various DC-DC topologies.
Replacement Considerations
DigiKey lists the NCP5355DR2 as obsolete. Check for alternative package types or updated revisions from onsemi. Evaluate compatible half-bridge drivers with similar 2A output current and 9-18V supply ranges. Ensure pinout compatibility before substituting.
