The application discloses a
voltage division offset compensation
control circuit and a
voltage division offset compensation method. The
voltage division offset compensation
control circuit comprises: a voltage stabilizing circuit, which is used for sampling an output voltage VO to form a feedback voltage
signal, comparing the feedback voltage
signal with a reference voltage VREF, and generating an adjustment
control signal to adjust the output voltage VO. A compensation circuit is connected with a feedback node of the voltage stabilizing circuit, used for generating a compensation current IX based on the change of the output voltage VO, and injecting the compensation current IX into the feedback node of the voltage stabilizing circuit to offset the voltage division offset caused by the change of the output voltage VO, so that the feedback
signal maintains a
constant voltage division ratio under different output voltages. The application can eliminate the resistance voltage division error caused by the change of the output voltage in the voltage stabilizing circuit, and ensure the high-precision output of the voltage stabilizing circuit.
