Patents by Inventor Chu-Yi Chiang

Chu-Yi Chiang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • DC-DC controller and control method thereof
    Patent number: 8947065
    Abstract: A DC-DC controller and a control method thereof are provided. The DC-DC controller is coupled to an output stage. The output stage receives an input voltage and provides an output voltage. The DC-DC controller includes a transient boost circuit, a ramp oscillator, a combination logic circuit, a first comparator and a pulse width modulation (PWM) generator. The transient boost circuit generates an adjusting signal according to a variation of the output voltage. The combination logic circuit controls the ramp oscillator to generate a ramp signal according to the adjusting signal. The first comparator generates a first signal according to the ramp signal and an outputted feedback voltage related to the output voltage. The PWM generator generates a PWM signal according to the first signal, so as to control the operations of the output stage.
