Title:
POWER SUPPLY SYSTEM
Document Type and Number:
Japanese Patent JP2022144019
Kind Code:
A
Abstract:
To provide a power supply system capable of reducing a variety of PMICs and reducing development costs thereof.SOLUTION: A power supply system includes a single first semiconductor integrated circuit (PMIC 1), at least one second semiconductor integrated circuit (PMICs 2 to 6), a first transmission line 7, and a second transmission line 8. Each of the single first semiconductor integrated circuit and the at least one second semiconductor integrated circuit includes at least one output terminal configured to output an output voltage. The single first semiconductor integrated circuit is configured to supply a clock signal CLK to the at least one second semiconductor integrated circuit via the first transmission line. Based on the clock signal, any one of the single first semiconductor integrated circuit and the at least one second semiconductor integrated circuit is configured to transmit a data signal via the second transmission line to another one thereof.SELECTED DRAWING: Figure 1
