DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the HV designation matches the required input voltage range for your application. Check current availability status as supply may be limited. Ensure compatibility with existing PCB footprints for the 8-SOIC package. Validate RoHS compliance documentation if required for your manufacturing process.

DC DC Switching Controllers Selection Notes

Select this controller when wide input voltage tolerance is necessary alongside high efficiency at light loads. Compare against standard LTC1147 variants if lower input voltage ranges suffice. Consider thermal performance requirements given the 1.25A capability in an SOIC package. Evaluate external component selection for the 400kHz switching frequency to optimize size and efficiency.
