In this post I have explained about L298N dual H-bridge DC motor driver module which can be used to drive brushed DC motors and stepper motors with microcontrollers and ICs. Overview Modular circuit boards are best time savior for electronics designers which also reduce the prototyping errors. This is mostly preferred by programmers who write […]

2 Simple MOSFET Gate Driver Circuits using BJTs
Very often we see that output coming from a microcontroller, oscillator, comparator, or PWM stage is just not strong enough for driving a power MOSFET directly, it gives signal, yes, but gate does not respond properly unless some decent current reaches there. A MOSFET gate behaves like a small capacitor, so now unless that gate […]
A4988 Motor Driver Circuit Diagram with IC 555
In this article we now talk about a very simple but very useful stepper motor controller that uses one A4988 driver module and one 555 astable pulse generator. Overview Of The Circuit So we first see the main building blocks. We have one A4988 module that drives any small 2 phase stepper motor. We also […]
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 […]
