What is DID? DID is short for Digital InformaTIon Display. It is a new generation of liquid crystal display technology launched by Samsung Electronics in 2006. It is widely used in security monitoring in various industries (hydropower production scheduling, military command,
Pseudo-interrupt and pseudo-interrupt handling of LPC2292 Industrial Ethernet has better performance than the field bus, and is in the process of continuous development and improvement, so the development of industrial Ethernet-based equipment has good market prospects. The e
Introduction to MDN MDN is located between MCP and MS, and is composed of MDN management module MM, directory server DS (multi-directory server), virtual content server VCS and several PN nodes distributed in the network (denoted as P1, P2, P3 in the figure) The main function

Abstract: This note describes a dual tracking controller for a single I / O voltage and two core voltages. It describes how to apply the circuit to one or many core voltages. Principles covered include: the need for tracking, pracTIcal circuits, controller funcTIons, selecTIon
Abstract: Circuit based on a buck / boost converter controller regulates current to a white LED, despite an allowed variaTIon of input voltage from 2.7V to 16.5V. The advent of high-power LEDs capable of replacing incandescent bulbs has produced a need for circuits that effici
Abstract: The circuit drives a high-power white LED (WLED). When the temperature is too high and the thermistor has an open or short circuit fault, the LED will be turned off. Summary of white LED driver with high temperature protection function: The circuit drives a high-powe
Abstract: Cold cathode fluorescent lamps (CCFL) are used as white light sources to provide backlight for liquid crystal displays (LCDs). CCFL can provide many good features, but also consider their unique characteristics in order to maximize their usability. This application no
