2 Compact 12V 2 Amp SMPS Circuit for LED Driver
In this post I will comprehensively discuss a 2 simple 12V 2 amp SMPS circuit using the IC UC2842. We study a 2 amp flyback design by evaluating various formulas, which provides the exact selection details for the transformer winding and the parts specifications. Design#1: Introduction The first design is based on the versatile IC VIPer53-E. […]
7 Watt LED Driver SMPS Circuit – Current Controlled
The presented 7 watt LED driver circuit is an SMPS based non-isolated, transformerless circuit which ensures a safe current controlled output for the attached LED, it is very affordable to build without involving complex transformer winding. Constant Current and Load Regulation Objective The aim behind the design of the IC TPS92310 (from TEXAS INSTRUMENTS) is […]
Random LED Number Generator for Gambling Application
In this post I have explained a random LED number generator circuit consisting of a 4 x 5 LED matrix, numbered from 1 to 20. On pressing a push button these LEDs begin illuminating randomly, until finally a single LED corresponding to a specific number remains illuminated. Thus, this random LED number generator can be […]
220V/120V LED String Light Circuit using a Single Capacitor
In this post I have explained how to make a LED string light which can be operated from 220V mains through a single inexpensive PPC capacitor. The idea was requested by Mr. Basit Momin.WE STRICTLY CAUTION YOU THAT YOU BUILD THIS CIRCUIT ONLY IF YOU ARE AWARE OF THE DANGERS OF MAINS AC AND KNOW […]
200, 600 LED String Circuit on Mains 220V
In this post I have explained the construction of a 200 to 600 LED circuit project, using series parallel LEDs for creating an alphabetical display sign board. The idea was requested by Mr. Mubarak Idris. Circuit Objectives and Requirements I need a blinking LED light that show”WELCOME TO” blink and then “COLLEGE OF ENGINEERING” base […]
