Conclusion

The PDN-6x power design is composed of four variants (G, H, J, and K) to provide peak power for the AM68x processor line and the SK-AM68 Processor Starter Kit uses PDN-6H scheme. The highly integrated LP8733x PMIC is the central power device that enables low cost, reduced area power designs for non-safety, industrial AM68x processor applications. A PDN selection guide outlined different AM68x use cases along with the PDN-6x base and optional features to assist selection of an AM68x power design. Example power maps for each PDN variant were provided to clarify different power designs and help accelerate the design process.
