To emulate the natural soft start of an incandescent bulb, this circuit makes use of the thermal-foldback protection built into an LED-driver IC (MAX16832). It thereby avoids the annoying and almost i
This application note presents an LED driver solution for MR16 and similar retrofit lamps. The circuit drives LEDs from a 12VAC input. The solution works with both magnetic and electronic transformers
The long strings of LEDs commonly found in TV and display backlighting, street lights, and parking garage lights require a current driver capable of producing high voltages. This reference design prov
LCD Driver IC 測試方法及其對測試系統提出的挑戰LCD顯示器件在中國已有二十多年的發展歷程,已經從最初的以數字顯示為主轉變為以點陣字符、圖形顯示為主。LCD顯示設備以其低電壓驅動、微小功耗、能夠與CMOS電路和LSI直接匹配、具有極薄的扁平結構、可以在極亮的環境光下使用、工藝簡單等等特點成為了極有發展前景的顯示器件。 LCD顯示器件種類繁多、發展迅速,從種類到原理、從結構到效應、從使用方式到應用范圍差異很大,從測試原理上來說也就會有一些不同,目前比較常用的是STN和TFT的LCD顯示器件。由
