Abstract

The invention provides an electronic device and an input voltage compensation method. The electronic device can be coupled to a feedback end of a voltage regulator through an additional circuit pin, thereby reducing the impact from the voltage drop between the voltage regulator and the electronic device, and reducing the power loss when the electronic device operates at a low-efficiency mode. In addition, the electronic device also can generate the feedback voltage through an internal resistor array, and transmits the feedback voltage to the voltage regulator, so as to control the voltage regulator to regulate the voltage to be an output voltage according with the expectation of the electronic device.

Description

technical field [0001] This case relates to an electronic device, in particular to an electronic device with an input voltage compensation function and an input voltage compensation method. Background technique [0002] When the electronic device is disposed on a circuit substrate (such as a PCB), a circuit pin of the electronic device is coupled to an output end of a voltage regulator to receive an output voltage provided by the voltage regulator. For an electronic device made of an integrated circuit (IC), when the system starts up, the circuit pins of the electronic device receive the output voltage provided by the voltage regulator. However, in conventional implementations, the output terminal of the voltage regulator is coupled to its own feedback terminal, so as to adjust the output voltage. Therefore, the wiring path on the circuit board and the parasitic impedance generated by the wire bonding inside the electronic device will lead to the phenomenon of IR drop, whic...
