STEVAL-ILD003V1模拟墙壁调光器为基于TS820（欧版220V）CFL/ LED灯具。STEVAL-ILD003V1演示板提出了利用一个敏感的可控硅TS820-600FP，一个低成本的模拟调光器的拓扑结构的设计。调光器可驱动典型的低功耗灯，特别是节能灯和LED可调光灯具。The STEVAL-ILD003V1 demonstration board is designed to propose a low-cost analog dimmer topology using a sensitive SCR TS820-600FP. The dimmer can drive typical low-consumption lamps, particularly CFL and LED dimmable lamps.Through-hole technology is used for the most important components such as LC filter, gate resistor, turn-on delay capacitor, etc., in order to allow board modification, if needed.The STEVAL-ILD003V1 eliminates flickering thanks to its continuous current applied through the sensitive SCR gate. This dimmer could easily replace a standard low-cost analog Triac light dimmer using a Diac-controlled circuit.
