DC DC Switching Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm the IS-1 variant matches the required electrical specifications against the official datasheet. Ensure compatibility with the intended operating temperature range and package dimensions before finalizing procurement decisions.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring high output currents up to 20 A with minimal external component count. The fixed 300 kHz frequency allows for smaller passive components compared to lower frequency alternatives. Consider the input voltage range suitability for systems powered by 12V, 24V, or 48V buses.

DC DC Switching Controllers Part Context

This part belongs to the LTC1735 family of synchronous buck regulators designed for high-current applications. It shares architectural similarities with other members but offers specific performance characteristics tailored for robust power delivery. The series is known for integrating power switches to reduce solution size.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include the LTC1735IS-1#PBF for tube packaging or the LTC1735IS#PBF if the -1 subcode variation is not strictly required. Verify pinout compatibility and electrical parameters against the target design requirements before substitution.
