The TPS65219 PMIC is a cost and space optimized solution designed to power the AM243x microcontroller and its principal peripherals. The TPS65219 PMIC has flexible mapping and comes in several factory programmed variants to support different AM243x use cases. The AM243x is within the Sitara™ family of Arm® processors, and provides highly flexible, real-time, and low latency processing for a broad range of industrial, enterprise and communications applications. These processors come in an array of variants with up to four Arm® Cortex® -R5F cores each. Powering a microcontroller such as the AM243x 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.
