Abstract
A novel synchronous primary-side dimming control scheme is proposed an d tested for a cold-cathode fluorescent lamp (CCFL) driver circuit for liquid crystal display (LCD) back-light illumination display applicat ion. This new control scheme features high efficiency, even-dimming se nsitive adjustment, even-brightness control for a two-lamp system, les s lamp flickering problems, stable feedback control, and simplicity. A n analysis of the circuit is given, from which a design example is pre sented.
