DC DC Switching Controllers Procurement Notes

Verify that the specific suffix 'G4' corresponds to lead-free packaging requirements if mandated by your assembly process. Confirm the package type matches your PCB footprint, as this part number indicates a surface-mount variant distinct from through-hole options. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

DC DC Switching Controllers Selection Notes

Select this component when a dual-output PWM controller is required for isolated or non-isolated topologies. It is suitable for designs needing a 45% maximum duty cycle limit. Consider alternative packages like PDIP if through-hole mounting is preferred over the SOIC form factor provided here.
