5.3 AM243x (ALX Package) Single-PMIC Solution

Figure 5-5 shows an example power map using the LP87334D to power the core rails of the AM243x (ALX Package) processor. The AM243x (ALX Package) body size is 11 mm × 11 mm, and does not support LPDDR4 or DDR4 memory.

Figure 5-6 shows an example power map that utilizes two GPOs to sequence additional regulators TPS62822 (buck regulator) and TPS745 (LDO) for Ethernet PHY support. TPS62822 can power 1.1 V Ethernet PHY when enabled by GPO2, and can be substituted with TPSM82822, a module with a step-down converter with an integrated inductor. TPS745 can power 2.5 V Ethernet PHY when enabled by LDO0, as shown in the below example power map.
