DC DC Switching Controllers Procurement Notes

Verify the specific suffix #WPBF against the manufacturer's latest documentation to confirm lead-free status and RoHS compliance. Ensure the operating temperature grade matches the 'I' designation requirements for your specific environmental conditions. Cross-reference the package marking code to distinguish from similar variants within the LTC7817 family.

DC DC Switching Controllers Selection Notes

Select this controller when a compact solution for mixed buck and boost topologies is required. The 3MHz frequency allows for smaller inductors compared to lower frequency alternatives. Consider the 40V input limit and ensure it aligns with the system bus voltage. Evaluate thermal performance given the HFNQFN-28 package constraints for high-current applications.
