DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when ordering. Confirm the EUD grade meets the required operating temperature range of -40°C to +85°C for your application environment. Ensure compatibility with the 16-WFQFN (3x3) footprint during PCB layout. Cross-reference the datasheet for any recent product change notices regarding wafer fab location or material declarations before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component when a wide input voltage range up to 38V is required alongside high output current capability. The 500kHz switching frequency allows for compact passive component selection compared to lower frequency alternatives. Consider the thermal performance of the exposed pad QFN package for heat dissipation requirements. Verify that the control interface requirements, such as tracking and enable functions, align with system design needs.
