Procurement Notes

Verify the specific suffix IDD#PBF against the manufacturer datasheet to confirm the package type and temperature grade. Ensure compatibility with the intended PCB layout regarding the exposed thermal pad requirements. Confirm RoHS compliance status through official documentation before integration into production designs.

Selection Notes

Select this component when a single-output buck converter is required with an input voltage up to 36V. The adjustable frequency allows optimization for efficiency or size. Consider the 1A output limit and the thermal performance of the 12-DFN package relative to the expected load conditions and ambient environment.

Part Context

This part belongs to the LT3682 family of high voltage synchronous buck regulators. It shares architectural similarities with other members like the LT3680 and LT3686 but differs in output current capacity and package options. The series is designed for applications requiring robust performance across wide input voltage variations.
