LMR38020SQDDARQ1
by TI(德州仪器)The TI LMR38020SQDDARQ1 is a buck regulator used to generate a lower supply rail from a higher input rail. Layout matters for a switching regulator, so the package assignment is especially useful to inspect before routing. The downloadable files pair a nine-pin KiCad symbol with the SOIC-8_L4.9-W3.9-P1.27-LS6.0-BL-EP3.4 footprint, which has nine pads including the exposed-pad position indicated by its name. A 3D model is also included. This set is from a real ProtoFlow import, with the conversion checked in the editor. It can be opened directly in ProtoFlow while laying out the power section.
