The AM263x Launchpad and AM263x controlCard EVM designs both integrate a set of buck-converter, DC-DC regulators that may be useful as a reference power solution for some systems. This solution consists of a pair of TPS62913 buck-converter regulators for AM263x MCU core, system digital and analog I/O power, and a set of TPS74801 LDO for powering paired industrial Ethernet PHY.
Current and transient requirements of the DC-DC closed-loop and passive power plane and decoupling network are taken from the power consumption and transient loading tables: Table 2-3 and Table 2-4. Many DC-DC regulators can be matched to fit within these requirements and the maximum power consumption.
It is also recommended to use the power-good generation circuits available on these and similar DC-DC regulators to drive the power on reset (PORz) into the AM263x.
