includes four synchronous buck converters that regulate the input 5V down to various rail voltages required by the SoC, including VDD_CORE (roughly 1.0V), 1V8 , and 1V1_DDR . Raspberry Pi 4 Model B Full Schematic

: Power is typically supplied via a USB-C connector. The official schematic shows the CC1 and CC2 lines used for power negotiation. Early revisions (v1.1) had a known design flaw in this circuit where they shared a single pull-down resistor, which was corrected in revision 1.2 .
