1 Introduction

The AM68x processor line provides highly flexible, real-time, and low latency processing for a broad range of industrial applications. These processors come in an array of variants with up to two Arm®Cortex® -A72 cores and up to six Arm®Cortex® -R5F cores each. TI has multiple power designs using different power management ICs (PMIC) to support an end product's desired feature set.

The LP8733x power design described below provides four Power Distribution Network (PDN) variants to supply AM68x processors according to a system's desired features. A selection guide has been created that outlines PDN features, optional functions, flexibility and design advantages for each PDN-6x variant. The power design highlights the value and flexibility of using a PMIC centric power design.
