1 Introduction

The TPS65219 PMIC is a cost and space optimized solution developed to power the AM62x processor and its principal peripherals. TPS65219 has flexible mapping and comes in several factory programmed orderable part numbers to support different AM62x use cases. A hardware solution is readily available with the AM62x SK EVM. The AM62x is the latest in the Sitara™ family of Arm® processors, built with features to support embedded 3D graphics acceleration, dual display interfaces, and extensive peripheral and networking options. To be used in applications from Human Machine Interfaces (HMI) to 3D Point Cloud, this processor provides powerful computing while supporting power management features designed for portable or power-sensitive systems. The AM62x processor requires at minimum power for seven main rails. These include the core supply (VDD_CORE), RAM supply (VDDR_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.
