This guide details a power solution for the AM335x application processor with a TPS650250 Power Management Unit (PMU) or Power Management IC (PMIC). Portable application solution size demands a high level of integration and the AM335x requires at least three different voltage rails with specific power-on and power-off sequencing requirements. The TPS650250 is a highly integrated power solution that can provide the 1.8V, 3.3V, and 1.1V rail signals required by the AM335x.
