Abstract
The invention discloses a PWM voltage regulator circuit, a regulating method using the same, and a liquid crystal display comprising the same. The PWM voltage regulator circuit comprises a PWM voltage regulating module, a feedback module connected with the PWM voltage regulating module, and a control module connected with the feedback module. The control module comprises a programmable image processing chip; and the programmable image processing chip comprises at least one memory bank (bank) and an access circuit. A feedback comparing reference voltage data of the PWM voltage regulating module is stored in a memory bank (bank), and the memory bank (bank) is connected with the feedback module by the access circuit. The invention can quickly regulate a PWM chip output voltage, increase IC generality, and reduce the product cost.
