Principio de funcionamiento
Five buck converters use PWM/PFM mode switching for high efficiency across load range, powering core, DDR, and I/O rails. Eight LDOs provide clean power for analog domains and peripheral I/O. I2C interface enables dynamic voltage scaling (DVS) for CPU frequency scaling. Power sequencing is programmable for proper SoC boot-up.
