DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF confirms tape-and-reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc., formerly Linear Technology. Ensure the part number matches the exact 3.3V fixed output variant. Check RoHS compliance status against current environmental declarations. Validate the 16-SOIC package dimensions for PCB footprint compatibility.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring synchronous rectification to improve efficiency. The fixed 3.3V output simplifies design compared to adjustable variants. Consider the 400kHz switching frequency for balancing component size and noise. Verify that the load profile benefits from Burst Mode operation. Ensure the input voltage stays within the specified 3.5V to 18V range.

DC DC Switching Controllers Part Context

This part belongs to the LTC1266 series of synchronous switching regulator controllers. The series includes adjustable and fixed voltage variants such as the IS-5 and standard IS versions. The family is characterized by its ability to drive both N-channel and P-channel external MOSFETs efficiently.
