6 Summary

The TPS6282x and LM61460-Q1 buck converters along with the TPS74518, TLV7103318 and TLV75518 LDOs provide a BOM optimized, discrete power solution for the AM62x. This document details the required external components for the discrete ICs as well as the sequencing connections between them to meet the power on/off requirements of AM62x. Simple logic AND and OR gates along with an RC delay helps to achieve the correct sequencing between the VDD_CORE and VDDR_CORE rails. This document can be used as a reference for choosing a series of discrete devices for powering the AM62x.
