LINEAR LED CONTROLLER ICS TARGET DIMMABLE LIGHTING APPLICATIONS

Two linear LED controller ICs have been added to the BCR portfolio, by Infineon Technologies. The BCR601 has voltage feedback to the primary side (also known as active headroom control or AHC), for cost effective and power efficiency LED driver applications. The BCR602 targets dimmable LED applications such as light engines, modules and strips. It has a wide voltage range […]

Simple SSR has zero-cross on/off switching

This Design Idea is a solid state relay (SSR) which uses a triac to switch AC loads at high current. There are plenty of simple SSR circuits available, but this may be the simplest circuit that achieves turn-on and turn-off only when the AC line voltage is near zero. Figure 1 AC SSR schematic with

INFINEON GALLIUM NITRIDE POWER DEVICES

Infineon adds GaN (Gallium Nitride) to its power portfolio: CoolGaN™ and GaN EiceDRIVER™ ICs. The next essential step towards an energy-efficient world lies in the use of new materials and technologies. Wide bandgap semiconductors enable greater power efficiency, smaller size, lighter weight, lower cost, or all together. Infineon is uniquely positioned in the power semiconductor

Two bits per transistor: high-density ROM in Intel’s 8087 floating point chip

The 8087 chip provided fast floating point arithmetic for the original IBM PC and became part of the x86 architecture used today. One unusual feature of the 8087 is it contained a multi-level ROM (Read-Only Memory) that stored two bits per transistor, twice as dense as a normal ROM. Instead of storing binary data, each

Single Atom Transistor With Ultra-low Power Consumption

Karlsruhe Institute of Technology (KIT) researchers in Germany have developed a single-atom transistor that can reduce the power consumption of electronic systems significantly. The device is being developed by Professor Thomas Schimmel and his team at the Institute of Applied Physics (APH). The single-atom transistor switches electrical current by controlled repositioning of a single atom in a gel electrolyte. The

Brand New BiCMOS Flexible Transistor

The transistor revolutionized the field of electronics, and paved the way for smaller and cheaper radios, calculators, and computers, among other things since its very first practically implemented device as a point-contact-transistor invented in 1947 and getting the Nobel Prize in Physics in 1956. Now, engineers from the University of Wisconsin-Madison (UW-Madison) have built the most flexible, fully-functional transistor in the world! The BiCMOS (Bipolar Complementary Metal Oxide

High- Frequency Transistor Amplifier Calculator

Common-Emitter and Common-Collector Transistor Amplifier Calculator for High-frequency Operation Analysis of the bipolar transistor amplifier at low-frequency is relatively easy, and several calculators exist online that do a good job. For high-frequency operation, there are fewer references available. For my projects, I like to build a reference spreadhseet where everything is in one place. This

TraId – Transistor type & pinout identifier

I’ve been a bit busy the last couple of weeks but I’ve now finished my 22’nd Project A Week. Maybe I have to change the name to PAAW instead (Project Almost A Week) ^_^ TraId is a really low cost version of the Part Ninja. It’s made to only identify the pinout and type (NPN/PNP)

Berkeley Lab makes graphene-MoS2 transistor

U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has developed a way to assemble transistors based on the 2D materials graphene and molybdenum disulfide. The method etches narrow channels in conducting graphene laid down on a silicon-dioxide substrate. These channels are then filled with a transition-metal dichalcogenide, or TMDC, or more specifically MoS2.
