The TPS65219 PMIC is a cost and space optimized solution developed to power the AM62x processor and its principal peripherals. This PMIC has flexible mapping and comes in several factory programmed orderable part numbers to support different use cases. The AM625SIP processor requires at minimum power for six main rails. These include the core supply (VDD_CORE), DDR PHY IO supply (VDDS_DDR), 1.8 V VDDA analog supply and the 1.8V/3.3 V IO supplies and analog IO rails (VDDSHV). Powering a processor such as the AM62x family demands requirements such as sufficient current headroom, tight transient requirements, and a number of rails that can be fully controlled for power up and power down sequencing. In the event of any inconsistency between any user's guide, application report, or other referenced material, the data sheet specification is the definitive source.
