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 测试方法及其对测试系统提出的挑战LCD显示器件在中国已有二十多年的发展历程,已经从最初的以数字显示为主转变为以点阵字符、图形显示为主。LCD显示设备以其低电压驱动、微小功耗、能够与CMOS电路和LSI直接匹配、具有极薄的扁平结构、可以在极亮的环境光下使用、工艺简单等等特点成为了极有发展前景的显示器件。 LCD显示器件种类繁多、发展迅速,从种类到原理、从结构到效应、从使用方式到应用范围差异很大,从测试原理上来说也就会有一些不同,目前比较常用的是STN和TFT的LCD显示器件。由
