Integrated analog dimming controller for 0–10V dimming system

0-10V dimming is popular in commercial building for energy management control. The 0-10V dimming system, circuit and operating principle are introduced. An integrated controller is presented which is capable of directly interfacing the 0-10V dimming circuit. It is suitable for the 0-10V LED driver design. The benefits include lower system cost, simple external circuit and easy implementation.
