O919A152TRGZTQ1 Allgemeine Beschreibung

The TPS65919-Q1 PMIC is a highly versatile power management integrated circuit designed to meet the demands of automotive electronic systems. With four configurable step-down converters offering up to 3.5 A of output current, this device is capable of efficiently powering a range of components including the processor core, memory, I/O, and LDOs. The integration of an internal 2.2-MHz clock ensures improved EMC performance, while the option to synchronize with an external clock through the GPIO_3 pin facilitates system-level synchronization for enhanced reliability
