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.
