This LED driver electronic circuit is designed using the NCL30100 compact switching regulator controller intended for space constrained constant current high−brightness LED driver applications where efficiency and small size are important. The controller is based on a peak current, quasi...

This article describes simple constant current driver module with fast PWM input that can be used for driving middle and high power LEDs. The module uses Taiwan Semiconductor TSC19376 LED driver, operates from 8 to 33 VDC and the output current can be configured from 0.1 to 0.5 A in several...

Регулировка яркости светодиодов осуществляется при помощи внешнего ШИМ-сигнала с выходным напряжением от 0,5 до 2,5В и частотой регулирования от 100Гц до 20кГц. Сигнал подается на DIM вход микросхемы PT4115. Если напряжение ШИМ-сигнала будет больше 2,5В, то выходной ток драйвера будет постоянным...

This scheme was manufactured powerful light-emitting diodes, up to 1500mA power supply. The scheme was taken by the classical buck or step-down DC / DC converter with schematiką gryžtamuoju connection by the current. The scheme used in the most economical and Lithuania stores (Evita lemon, RCL)...

The article presents a 32V, 3 amp SMPS circuit which may be specifically used for driving 100 watt LED modules, rated with the same specs. How to Wind the Ferrite Transformer The transformer is wound over a standard EE ferrite core having a central cross sectional area of at least 7 square...

The advent of high-power LEDs that can replace incandescent bulbs has produced a need for circuits that efficiently match the LEDs to available power sources (batteries, car electrical systems, etc.). The circuits should also be able to regulate and control the LED light output, despite...

High Efficiency 12V White LED Driver (C) G. Forrest Cook February 3, 2006 Introduction DC powered LED lighting circuits can vary from trivial single LED/series resistor combos to simple analog current regulators to more complicated switching power supply circuits such as this project. There is...
