摘要:几个电路的想法是为保护升压转换器的LED驱动器时的LED断开。 (没有保护的情况下,驱动器输出可以摧毁外部MOSFET和肖特基二极管) LED驱动器IC ( MAX1698 )和比较器( MAX9060或MAX9028 ) 。Maxim > App Notes > Circuit Protection Display Drivers Keywords: LED drivers, backlit displays, battery operation, circuit protection Feb 01, 2011 APPLICATION NOTE 4576 Protect LED Driver in Backlit Displays By:Massimo Caprioli Abstract:Several circuit ideas are presented for protecting a boost-converter LED driver when the LEDs are disconnected. (Without protection, the driver output can destroy the external MOSFET and Schottky diode.) An LED-driver IC (MAX1698) and comparator (MAX9060 or MAX9028) are included. A similar version of this article appeared in the July 6, 2009 issue of EE Times magazine. LEDs often serve as the light source in a backlighted display, and they usually operate with a low battery voltage such as that produced by two Ni……
