ADAPTIVE POWER SUPPLY CIRCUIT AND SYSTEM
A power supply system compatible with both USB 2.0 protocol and USB type-C specification. The power supply system monitors the die temperature. It is configured to 1) change the system mode from DCP mode to SDP mode or decrease an output voltage of a power stage; and 2) change resistance values of a...

| Zusammenfassung: | A power supply system compatible with both USB 2.0 protocol and USB type-C specification. The power supply system monitors the die temperature. It is configured to 1) change the system mode from DCP mode to SDP mode or decrease an output voltage of a power stage; and 2) change resistance values of a first pull up resistor and a second pull up resistor to decrease an output current capability if the die temperature is higher than the temperature threshold. |
