INTEGRATED CIRCUIT AND ELECTRONIC DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240345611 titled 'INTEGRATED CIRCUIT AND ELECTRONIC DEVICE INCLUDING THE SAME
The abstract of the patent application describes an integrated circuit with a power supply circuit that generates a supply voltage from two power source voltages, and a system load that operates by receiving the supply voltage through the power supply circuit.
- The integrated circuit includes a first low drop-output (LDO) regulator that generates a load current from the first power source voltage to the system load.
- It also includes a second LDO regulator that selectively generates a load current from the second power source voltage to the system load based on the voltage difference of internal nodes of the first LDO regulator.
Potential Applications: - This technology can be used in various electronic devices that require efficient power management systems. - It can be applied in portable devices, IoT devices, and other battery-powered electronics.
Problems Solved: - Efficiently managing power from multiple sources. - Providing stable supply voltage to the system load.
