Patent number: 10660176Abstract: A system for driving a light source includes a power converter and control circuitry coupled to the power converter. The power converter converts input power to an output voltage to power the light source. The control circuitry senses the output voltage and senses current of the light source. The control circuitry generates a control signal based on a voltage feedback signal indicative of a combination of said output voltage and said current of said light source, and controls the power converter by the control signal to adjust the output voltage.Type: GrantFiled: January 24, 2017Date of Patent: May 19, 2020Assignee: O2Micro Inc.Inventors: Jen-Chun Chen, Sheng-Tai Lee, Yung-Lin Lin
