Abstract: A power supply phase doubling system includes a pulse width modulation (PWM) controller and first and second phase doubling chips. The PWM controller outputs a PWM signal. The first phase doubling chip is operated at a power supply voltage and has a first PWM output pin to generate a first control signal and a second control signal according to the PWM signal, and generates a first output signal according to the first control signal. The second phase doubling chip is operated at the power supply voltage, has a second PWM output pin, and is configured to generate a second output signal according to the second control signal. The first and second phase doubling chips are respectively switched between a master mode and a slave mode according to a voltage level of the first PWM output pin and a voltage level of the second PWM output pin.

Abstract: A voltage detection device is provided. The voltage detection device includes a first voltage divider circuit, a comparison circuit, and a second voltage divider circuit. The first voltage divider circuit is configured to receive an input voltage and output a comparison voltage according to the input voltage. The comparison circuit is configured to receive the comparison voltage to compare the comparison voltage with a reference voltage and determine whether to change a trigger signal according to a comparison result. The second voltage divider circuit is configured to receive the input voltage. When the input voltage is greater than or equal to a predetermined voltage value, the second voltage divider circuit and the first voltage dividing circuit form a parallel structure to pull down the comparison voltage.
