This is a simple LED driver circuit using two 555s and a pair of NPN/PNP transistors to drive several LEDs meant to outline a small sign. Designed with my son for a St Patrick's Day project, in KiCAD.

独Infineon Technologies社は、LINトランシーバを内蔵したLEDドライバICの品ぞろえを拡充した。自動車の車室（キャビン）のインテリア照明に向けてRGB各色のLED素子を駆動する回路を搭載した。製品は全部で四つ用意した。このうち二つの製品は、電流源を集積し ...

台湾Taiwan Semiconductor Manufacturing Co., Ltd.（TSMC）は、CMOSロジック回路とLEDドライバの1チップ化を可能にする「BCD（Bipolar、CMOS、DMOS）」プロセスの提供を開始した。液晶バックライトや一般照明、車載照明などで使われる12～60V駆動のLEDに対応する。チップの動作 ...

This simple LED driver circuit allows us to drive up to seven LEDs by using a single NiMH (Nickel Metal Hydride) AA cell. The circuit produces voltage pulses at a much higher level than the input ...

This Idea for Design presents a simple and small solution for driving an LED to provide visual feedback in the presence/absence of a system’s power. Typical requirements for industrial LEDs. Designing ...

High-power LEDs challenge electronics engineers to design accurate and efficient, yet simple, driver circuits. Conventionally, driving high-power strings with accurate current requires dedicated ...

[Petteri Aimonen] created an omnidirectional LED safety light to cling to his child’s winter hat in an effort to increase visibility during the dark winter months, but the design is also great example ...

Toshiba has launched the TBD62064A series and TBD62308A series of highly efficient transistor arrays, featuring a DMOS FET type sink- output driver. These devices are claimed to be the industry’s ...

Abstract: 3D NAND technology is expected to continue advancing toward 1000-layer stacking in pursuit of ever-higher memory density per chip [1]. However, increasing the number of layers presents ...
