  "textContent": "A control method for controlling a battery charging circuit having at least one switch, includes: generating a first difference signal based on the difference between a charging current feedback signal and a charging current reference signal; generating a bias reference signal by proportionally integrating the first difference signal when the battery voltage is higher than a first threshold and less than a second threshold; generating a bias signal by proportionally integrating the difference between the sum of the bias reference signal and a system voltage reference signal and a system voltage feedback signal; generating a comparison signal by comparing the sum of the system voltage feedback signal and a ramp signal with the sum of the bias signal and the system voltage reference signal; and generating a control signal for controlling the at least one switch based on the comparison signal and a constant time period control signal.",
