Description

I am a beginner when it comes to electronics so I would appreciate your help with a simple project I am working on and have been struggling with for several days. Power MOSFETs are most often used a switches where they are turned fully ON or OFF to control a load such as a motor or high power LEDs. They are ideally suited for this because when the MOSFET is turned fully ON (Saturation Region), it has a very low resistance and can pass a lot of current without much power being dissipated in the device similar to a mechanical switch. When they are turned OFF (Cut-Off Region), they act as an open circuit much like a mechanical switch would when it is off.

If there are two voltages listed, the highest voltage will be the voltage at which the device is fully saturated and show the lowest resistance, often 10V. The lower voltage is often around 4.5V and shows the resistance if you were to drive it directly off of 5V logic. Having this specified implies that the device is at least partially 5V logic compatible even if it isn’t being driven to full saturation.R DS(on) : Static Drain-to-Source On-Resistance is the minimum resistance of the MOSFET when it is driven to the fully ON state known as the Saturation Region. The key to look for here is that R DS(on) may be specified at one or a couple of V GS voltages. You just apply power to the strip, and the LEDs light up. The following figure shows an example of a monocolor LED strip. This strip only produces white color. I used an optocoupler rather than a mosfet, which worked! But unfortunately at only around half the mA I need (80 vs the fans 130) so this isn't ideal. Now that you know what is the best LED strip for your project, you can go to Maker Advisor to find your strip’s best price.

frequencies you need to ensure shorter RC time constant in the gate-drive circuit. This usually means V GS : Gate Voltage is the voltage differential between the Gate and the Source which is how hard the MOSFET is being driven.

One meter of your analog LED strip can draw approximately 1A per LED pin when all red green and blue LEDs are at full brightness (which produces white). There are libraries that make it really easy to control the strip and make all sorts of crazy effects.

The power dissipated by a linear regulator is the voltage drop across the regulator x the current. If you feed 24V into a 12V regulator it will get hotter than if you feed-in 14V. The amperage rating can be misleading. A 1A voltage regulator can overheat at less than 1A depending on how much voltage is dropped across it. When it comes to LED strips, the main difference is between analog and digital LED strips. Analog and digital LED strips work differently and produce different results. So, whether you need an analog or a digital LED strip will depend on the project you want to build. Waterproof or not. The LED strips can be waterproof or not. The waterproof LED strips are coated in a clear silicon as the strip shown below. I have noticed that when using the IRLB8721, my LEDs are always on, and I am not able to switch them off. I did make sure not to mix up the Drain and Source, yet still not working.It is to my understanding that I need a logic level mosfet with an RDs(on) of 3.3V or less, but I am really struggling to find one readily available in Australia... In this post we’ve shown you the main differences between the various types of LED strips out there.

The very low ‘ON’ resistance means that there is very little voltage drop through the device and that also helps to keep power dissipation down.When it comes to analog strips, there are analog RGB LED strips and monocolor LED strips. Analog Monocolor LED Strips Alternatively I have a couple of 2N3904 transistors available but I am not entirely sure how I can use these without frying them. V DS : Drain-To-Source Voltage is the maximum voltage that the device can be used to switch. If you’re switching 12V, you need a device with a V DS> 12V and usually you want something with a fair amount of safety margin. These strips have four pins you need to connect. One red channel, one green channel, a blue channel and power. I have tried this with a IRLB8721 mosfet, but realized it needs a higher voltage than what the GPIO can provide. The most suitable one I could find then was the IRF3205, seeing that it is used more frequently with Raspberry PI/Arduino applications, but unfortunately this is also not working. It seems like my GPIO voltage is still too low.
