SNVU698B September 2020 – December 2020 LMQ61460-Q1
6.3 Load Regulation
This section provides efficiency plots for the board with LMQ61460AAS populated for Auto mode efficiency and LMQ61460AFS populated for FPWM mode efficiency. For 2.1-MHz data, the output stage has to be changed from the default BOM. The inductor (L1) selected was XEL5030-102MEB.
