XL6009 Buck Boost Converter

Introduction

Hey there in this session we will discuss how the buck boost converter works, here I am using XL6009 module and upgrade to buck boost converter.

Modified Inductor

XL6009 Boost Converter Module

Upgrading XL6009 Module

First we need toroid inductor from old SMPS filter, now make 25 turns of 0.7mm copper wire with two wires hence we got two coils of same turns as shown in figure.

Make Dual Coil inductor of 25 turns each

After this we have to remove the old inductor from xl6009 module and then we got two PCB points at which we will connect our modified inductor.

Remove the old Inductor from XL6009 module

Now connect the wire of both coils of inductor as shown in figure, the first coil wires connect between +VCC input and other to SW i.e. switch pin of XL6009 IC. And other coil wire will connect between input -Ve(GND) and diode pin.

After connecting the inductor to XL6009 module it looks like in figure.

SG/KA3525 PWM Controller

Introduction Hey everyone in this session we learn how to use KA/SG3525 IC to make PWM controller circuit having feedback, low voltage and over heating protection. Components So lets take look at components we need to make this circuit - 1.SG/KA3525 IC 2.LM358 IC 3.LM555 IC 4.10K NTC 5.Variable resistor - 10K*4, 500K*1 6.16-pin, 8-pin IC Base 7.Capacitors - 1nF*2, 100nF*4, 2.2uF*1) 8.Resistors - 100R*1, 220R*2, 1K*10, 5.6K*1, 10K*6, 15K*2, 100K*1 9.BC547*1 10.LED*2 11.Push Button*1 12.Zero PCB Working In this circuit we used SG3525 to make PWM controller and use...

How to use Hall Effect Sensor

How To Use Hall Effect Sensor Introduction : We will talk about hall sensors and their uses here I am using A3144 sensor this sensor has 3 pins VCC, GND, and OUTPUT it works on 5v dc its output is open collector so we get negative output when passes near magnet and this is digital sensor so you can use it directly with your projects it means no need of any comparator. And this sensor is used in BLDC motor, Fridge door automatic light, magnet pole detection etc. Watch Practical experiment Video of this Sensor . Pinout of A3144 : Circuit diagram : Buy Electronics components at very cheap price : Quartz Components 1) A3144 Hall Sensor 2) Leds 3) Resistors 4) 5v SMPS 5) Breadboard 6) Breadboard Jumper Wires 7) Crocodileclips
