Abstract: A protective circuit is provided. The protective circuit includes a charging unit, a voltage regulating unit, and a comparing unit. The charging unit receives a rise signal and an over-current signal, and outputs a first reference voltage. The voltage regulating unit receives the first reference voltage and adjusts an output voltage according, to the first reference voltage and a feedback voltage. The comparing unit receives the feedback voltage and compares the feedback voltage with a first threshold voltage to determine whether to output the rise signal to the charging unit.

Abstract: A voltage regulator circuit includes a soft start module, a pulse width modulation (PWM) module, and a voltage regulator module. The soft start module is used to receive a current feedback voltage corresponding to an input current, and compare the current feedback voltage with a comparison voltage, so as to output a switching signal. The PWM module is used to receive a clock signal and the switching signal, and determine a first PWM signal and a second PWM signal outputted by the PWM module is a high voltage level or a low voltage level according to the clock signal and the switching signal. The voltage regulator module is used to receive and adjust an output voltage corresponding to the first PWM signal and the second PWM signal.
