How to Design Simple LED Driver Circuits
In this article I have explained how to design your own customized, simple LED driver circuits at home. We will learn how to calculate specific LED configurations for applying the LEDs with appropriate LED driver power supplies. In these driver power supplies I have explained two concepts one by using SMPS boards and the other […]
SMPS 50 watt LED Street Light Driver Circuit
The post presents an SMPS based LED street lamp driver circuit which can be used for driving any LED lamp design right from 10 watts to 50 watts plus. Using the IC L6565 The proposed 50 watt (and higher) LED street light driver circuit uses the IC L6565 as the main control device, which is […]
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 […]
IC IR2184, IR21844 Half-Bridge Driver Circuit Diagram, Datasheet, Working
In this article we are going to learn about one very useful IC called IR2184 or IR21844. This one is a smart half-bridge gate driver IC which we can use for driving both high-side and low-side MOSFETs or IGBTs, mainly when we are making full bridge inverters, or DC motor controllers, or even induction heater […]
