Principio de funcionamiento<\/h2>\n

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.<\/p>\n
